About Accuracy
Last updated: April 2026
Learn about the accuracy sources, applicable scope of each feature, and why results from different features may not always align for the same person.
1. The Most Important Thing First
Tideris is not a single feature. It consists of multiple independent modules, each analyzing different dimensions with different applicable scenarios — so results naturally won't be identical.
Think of it like weather information: one source says "temperatures dropping today overall," another says "rain at your exact location at 3 PM." Both are true, just at different levels of detail.
Similarly:
- Free features focus on "how today's energy affects a group of people in general"
- Personal chart features focus on "your individual state"
- Divination features focus on "the current trajectory of a specific matter"
- Synastry features focus on "the interaction dynamics between two people"
So when the same person sees different results across features on the same day, it's usually not conflicting data — it's different analytical dimensions.
2. Where Does Accuracy Come From?
Different features derive accuracy from different sources, roughly divided into four layers:
1. Fixed Rules Layer
Results primarily from deterministic rule calculations. Same input yields consistent base results that don't change randomly on refresh. These features typically have the highest stability, suitable for quick daily reference.
2. Structural Layer
Results built on established chart, hexagram, or formation structures. Once the underlying data is determined, it's inherently stable and serves as the foundation for subsequent analysis.
3. Comprehensive Interpretation Layer
Results from comprehensive judgment on stable structural foundations. Core directions are usually stable, but when multiple signals appear simultaneously, analytical emphasis, phrasing, and prioritization may vary.
4. Input Quality Layer
Whether birth information is complete, whether questions are specific, and whether the same question is asked repeatedly — all directly affect result precision and stability.
In short: the closer to the fixed rules layer, the more stable the results; the closer to the interpretation layer, the more personalized and in-depth. Stability and personalization depth are different things — both have value.
3. How to Understand Each Feature?
🀄Five Elements Dressing Guide (Daily Free)
What it analyzes
The overall Five Elements energy of today, providing color, direction, and timing suggestions.
What determines the results
Derived from rule calculations based on the day's time correspondences — a general-level result.
What's more stable
Color suggestions, directional tips, and timing hints are highly stable. Wording may vary slightly, but directions are usually consistent.
How to interpret it
It answers "what rhythm is today generally better suited for," not a personal chart analysis.
🐭Chinese Zodiac Daily Fortune (Daily Free)
What it analyzes
The relationship between your zodiac sign and today's overall cosmic timing.
What determines the results
Base results come from stable rules — the same zodiac seeing the same base conclusions on the same day is by design.
What's more stable
Star ratings, clash warnings, and basic reminders are relatively stable. Text descriptions may have slight variations, but judgment directions usually remain unchanged.
How to interpret it
It's more like "whether today is generally favorable for your zodiac sign," not a deep personal chart judgment.
♊Constellation Daily Fortune (Daily Free)
What it analyzes
Daily-level trends, reminders, and rhythm awareness.
What determines the results
The base layer has stable rule support; comprehensive descriptions integrate more information.
What's more stable
Base trends are relatively stable; when multiple influences appear simultaneously, interpretation emphasis may vary.
How to interpret it
Best used as daily reference to quickly grasp the day's atmosphere — not for demanding precise event predictions.
📜BaZi Chart Reading
What it analyzes
The foundational chart structure corresponding to your birth information — the starting point for many personal analyses.
What determines the results
Determined by birth year, month, day, and hour. Once the base chart is cast, it's highly stable.
What's more stable
The chart structure itself has the highest stability. It's a "factual foundation," not an immediate judgment of today's fortune.
How to interpret it
Think of it as the foundation for personal analysis. Subsequent fortune, specialty, and relationship analyses all build on this layer.
📅BaZi Daily / Weekly / Monthly / Annual Fortune
What it analyzes
How time progression maps onto your personal chart, revealing phase states and rhythm changes.
What determines the results
Built on your personal chart foundation, combined with current time period for comprehensive analysis.
What's more stable
Chart foundation and directional judgments are usually stable; finer rhythm and prioritization may have some interpretive range.
How to interpret it
It answers "what's the overall state and focus for you during this period," not "everyone with the same zodiac has the same day."
💎BaZi Specialty Analysis (Wealth / Career / Love / Health)
What it analyzes
Focuses on a specific dimension for deeper structural analysis.
What determines the results
Comprehensive judgment on your personal chart foundation, focused on the specialty's specific concerns.
What's more stable
Core directions, long-term tendencies, and main tensions are usually stable; the more specific and short-term, the more factors come into play.
How to interpret it
Best for viewing trends, priorities, risk points, and action directions — not as absolute promises about specific event outcomes.
🪙Liu Yao Divination
What it analyzes
"How is this matter trending right now."
What determines the results
The hexagram structure formed at the moment of inquiry is the foundation, with subsequent analysis built upon it.
What's more stable
The hexagram itself is fixed; comprehensive extraction of fortune, obstacles, and turning points has some analytical range.
How to interpret it
Best for answering specific questions. The clearer the question, the more focused the result. Vague questions lead to broader interpretations.
🌀Qi Men Dun Jia Divination
What it analyzes
Situation, pathways, timing, and action rhythm.
What determines the results
The formation structure at the moment of casting is the foundation, with strategic judgment built upon it.
What's more stable
The formation itself is fixed; when multiple signals appear simultaneously, strategic priorities and path choices have some interpretive range.
How to interpret it
Best for understanding "how to assess the situation, how to proceed, where to start" — focusing on dynamics and rhythm rather than single-point conclusions.
🌸Synastry Analysis
What it analyzes
The interaction structure, compatibility points, friction areas, and rhythm differences between two people.
What determines the results
Based on both parties' information, analyzing interaction patterns at the relationship level.
What's more stable
Basic relationship structure is usually stable; comprehensive compatibility and interaction tendency judgments have some interpretive range.
How to interpret it
Best for understanding "why two people interact this way," not for making absolute relationship verdicts.
4. Why Might the Same Person Get Different Results from Different Features?
Because they're answering questions at different levels.
- Free daily features look at the general level
- BaZi personal fortune looks at the individual level
- Liu Yao and Qi Men look at the event level
- Synastry looks at the interaction level
A simple example:
If a particular day's overall cosmic timing is weak for a certain zodiac, the zodiac fortune might give a cautious conclusion. But if that specific user's personal chart happens to handle this energy well, their BaZi daily fortune might not be bad — it could even be stable.
These two results don't conflict. The former describes "the general environment for this group today," the latter describes "your actual experience mapped to today."
The deeper into personal dimensions, the more personalized the conclusions. This isn't contradiction — it's the normal variance that comes with increased analytical precision.
5. What Affects Accuracy?
1. Incomplete Birth Information
For BaZi and synastry features, more complete birth information usually means more stable results. When birth hour is unknown, finer-grained judgments become coarser.
2. Vague Questions
For divination features like Liu Yao and Qi Men, clearer questions lead to more focused results. Overly vague questions yield more directional judgments.
3. Repeated Inquiries on the Same Matter
Asking the same question repeatedly in a short period often reduces reference value. Divination features work best with "one focused question at a time."
4. Treating Trend Tools as Precise Prophecy
Metaphysical features are better suited for viewing trends, rhythms, structures, relationships, and key variables — not for promising precise event outcomes at specific moments.
5. Cross-comparing Different Systems Item by Item
BaZi, Liu Yao, Qi Men, and constellations are different analytical systems. Each excels at answering different questions and shouldn't be expected to match point by point.
6. What Are These Features Best and Least Suited For?
Best suited for:
- Trends, rhythms, structures, relationships
- Risk points and adjustment directions
- What to focus on right now
Not suited for:
- Absolute event guarantees
- Precise outcomes at specific moments
- Using one feature to replace all others
- Treating metaphysical results as the sole basis for real-world decisions
Tideris is best used as a "reference framework for viewing problems" — helping you understand trends, calibrate rhythm, and see relationships and priorities, rather than making all real-world decisions for you.
7. How to Best Use These Results?
- Use free features as lightweight daily reference
- For personal chart features, focus on trends, structure, and phase priorities
- For divination features, ask one clear question at a time
- For synastry, focus on interaction patterns and friction points, not just a single score
- When different features show variance, first check if they're answering the same level of question

9. Final Thoughts
What Tideris aims to do is not make complex content sound mystical, but to clearly explain what each feature is best at answering.
When you use the right feature, provide more complete input, and ask more specific questions, results are usually more helpful.
When different features show variance, don't rush to interpret it as contradiction. Often, they're simply answering different questions from the general, individual, event, and relationship perspectives.
