User cannot identify their weaknesses: Provide a self-assessment protocol: record themselves performing the sport (phone video is sufficient), compare to instructional reference material for their level, and look for the first point where their movement diverges from the reference. Alternatively, suggest a single session with a qualified coach for an initial assessment.
User has limited practice time (under 2 hours per week): Focus all practice time on the single most impactful sub-skill. Eliminate game play from sessions and dedicate 100% to deliberate drill work. Progress will be slower but still measurable. Set milestones at 4-week intervals instead of 2-week intervals.
User is learning a completely new sport from zero: Skip the assessment step (all domains are at 1). Instead, identify the one foundational skill that enables all others in that sport (e.g., ball control in soccer, floating in swimming, grip and stance in golf). Build the entire first 12-week cycle around that foundational skill. No game play until Stage 3.
User has hit a plateau and stopped improving: Plateaus typically indicate one of three issues: (a) practice is too easy -- increase difficulty or add decision-making pressure; (b) practice is not specific enough -- add more contextual and competition drills; (c) a prerequisite skill is limiting progress -- reassess and look for a hidden weakness in a supporting skill domain. Recommend varying practice conditions (different partners, different environments) to break pattern dependency.
User practices a solo sport (running, swimming, golf): Adjust the competition integration stage to focus on personal benchmarks and simulated pressure (time trials, score tracking over rounds, race-pace sets). Replace partner drills with self-monitoring drills: video recording, metric tracking, and comparison to previous performances.
