Practice vs tournament
The classic tournament-day question: am I a choker? This recipe puts a number on the gap.
Prompt
Section titled “Prompt”Separate my sets into two groups by `isPractice`.
For each group, compute:- Total number of sets.- Average `summaryTotalBuoys` per set.- Best pass overall (highest `lineOffUs` where `buoyCount >= 4`).- Average best line off per set.
Best pass per set = longest `lineOffUs`, tiebreaker highest `buoyCount`.Exclude draft passes and `autoGenerated: true` passes.
Output a markdown table comparing the two groups side by side.
Then in 2-3 sentences, tell me whether I perform better in practice ortournaments and quantify the gap (e.g., "0.4 of a line shorter on averagein practice").Example output
Section titled “Example output”| Metric | Practice | Tournament |
|---|---|---|
| Total sets | 87 | 14 |
| Avg total buoys per set | 18.4 | 14.1 |
| Best pass overall | 5.0 @ -35 | 4.0 @ -32 |
| Avg best line off | -31.6 | -29.8 |
You ski about 0.4 of a line shorter in practice than in tournaments on average, and your peak practice pass (-35) hasn’t shown up at a tournament yet — a real but modest tournament-day gap.
Follow-ups
Section titled “Follow-ups”“By season (use
account.seasonStartMonthDay/seasonEndMonthDayto define windows), has the practice-vs-tournament gap widened or narrowed over time?”
“Show me my 5 best practice passes that I’ve never matched in a tournament. List set ID, date, line off, speed, buoy count, ski site.”
“For tournament sets specifically, group by
tournamentName. Which tournaments do I score highest at?”
Variations
Section titled “Variations”Tournament round effect. Slalom tournaments usually have multiple rounds. Group tournament sets by tournamentRound and check whether you’re a slow starter (round 1 weak, round 2/3 stronger) or a fader.
Pre-tournament practice. For each tournament, find the practice sets in the 7 days leading up to it. Does strong practice predict a good tournament, or is the relationship noisy?
Confidence interval. Ask the AI to compute the standard deviation of your best line off per set in each group. A wide tournament SD means you’re inconsistent; a narrow one closer to your practice average means the gap is real.
