How BTKP works

How an event is organised

One line, biggest to smallest:

Community → Season → Event → Round → Match → Players

Community: A club. BTKP is one community; the platform can run others.
Season / Tournament: Groups many events and keeps a running points board. A season is ongoing (e.g. “BTKP Season 2”); a tournament is a bounded competition. (A plain tag just groups events, no standings.)
Event: One occasion — a single morning or evening, a few courts, ~2 hours. This is what you import.
Round: One rotation within an event — everyone plays, then we re-pair.
Match: One contest on one court: two sides, played to a points total.
Player: A person in the roster. Claim your profile to add a photo and see your stats.

We say match for one contest (not “game”), and event for the whole occasion (not “session” or “night”).

Formats

Mexicano (individual) — partners rotate every round, pairing close scores so matches stay even. Your results are your own.

Fixed Partner (team) — you keep the same partner the whole event; results belong to the pair.

Standings

Each match is played to a points total. The all-time leaderboard adds up every event; a seasonboard adds up only that season's events and can rank by points or by wins. The ladder below is separate — it's a skill estimate, not a points total.

Form — points index

Points index is a per-event score for how you did relative to everyone who played that event — so different events compare fairly.

points index = your points ÷ the event's average points

1.0 is the event average. Above 1.0 means you scored above the field that event (e.g. 1.25 = 25% above average); below 1.0 means below it.

Why not just raw points? Raw points depend on how many rounds were played — a longer event gives everyone more. Dividing by the event average removes event length, so the number tracks how you did, not how long you played.

Individual events only. The chart uses your Mexicano (individual) events — in Fixed Partner your points are shared with a partner, so they wouldn't be your form alone.

The two lines. The faint line is each event's value; the bold line is a 3-event rolling average — the smoothed trend.

The skill ladder (rating)

The ladder is a dynamic skill estimate, not a points total. After each event it updates from who beat whom — beating stronger players moves you more than beating weaker ones.

The number (ordinal).We rank by a conservative score: roughly the bottom of your likely skill range (μ − 3σ). It rises as we collect more matches and become more certain — a new player starts low even if they're good, and climbs as they play.

The ± band (uncertainty). Shows how unsure we still are. Wide for new players, narrowing with more matches.

Provisional. Below 15 matches a rating is a rough guess, not a verdict. It settles after about 15 matches.

Relative to BTKP only.It ranks you within the BTKP pool — not comparable to Playtomic or any other community's number.

Honest limits. Mexicano events rebalance teams to keep matches close, which suppresses rating movement; fixed-partner results carry a cleaner signal. Ratings need volume to converge — a few events test the pipeline, not the ladder.
