The athlete is not an average
Population research can inform Tyzle, but the athlete's own evidence matters most. Personalization must be earned by data, not asserted by branding.
Philosophy
Better coaching follows better understanding.
Tyzle is built around a simple hypothesis: the athlete should be understood before training is optimized.
Life is part of the athlete
Work, family, travel, sleep, illness, equipment, motivation, and available time are not exceptions to training. They are part of the model.
Uncertainty should be honest
If evidence is limited, Tyzle should say so. False certainty is less useful than a clear explanation of what is known and what remains unresolved.
The athlete remains in control
Tyzle can support decisions, but the athlete is the final decision-maker. Consent, override, and clear boundaries matter more than automation.
The Three Laws of AIM
Public language for Tyzle's scientific constraints.
1
Evidence is preserved; understanding may be revised.
Historical observations should remain intact. New evidence can change current understanding without rewriting what happened.
2
Every recommendation must be traceable to evidence.
Important guidance should be explainable through reasoning, beliefs, measurements, and supporting evidence.
3
Tyzle seeks better understanding, not false certainty.
The goal is to reduce uncertainty honestly as evidence accumulates, not to produce confident-sounding answers before they are justified.
How that shows up
Readable principles, not internal architecture.
Evidence remains immutable
Activities and provider artifacts are kept traceable so future methods can reinterpret them without losing historical integrity.
Understanding may change
A belief is Tyzle's current explanation, not an absolute fact. Better evidence should improve or revise that explanation.
Recent evidence matters
Current-state understanding should reflect the athlete today. Historical evidence still matters, especially for context and era detection.
Recommendations should be explainable
Athletes should understand what Tyzle observed, what it inferred, what remains uncertain, and why a future recommendation is justified.
