Analyze training patterns, performance, and physiological data using advanced computational models.AUTO-ACTIVATES when user asks about:- Training status/progress ("How am I doing?", "How's my training?")- Load/overtraining ("Am I overtraining?", "Is my load too high?")- Performance questions ("Why did I fade?", "What's limiting me?")- Specific run analysis ("Why was my HR high?", "What happened yesterday?")- Race readiness ("Am I ready?", "Will I make my goal?")- Physiological zones ("What are my zones?", "What's my threshold?")- Recovery/freshness ("Should I run today?", "Am I recovered?")- Patterns/causation ("What's causing...", "What predicts my best runs?")PROACTIVELY WARNS when detecting:- ACWR > 1.3 (load spike)- TSB < -25 (fatigue accumulation)- Correlation shifts (relationship changes)- Form breakpoints earlier than usual- Recovery decline between intervals
