Turbo Kart Racers computed stats

Derived Turbo Kart Racers metrics, attached as the always-on computed property of the raw stats block: whenever player.stats.turboKartRacers is present, player.stats.turboKartRacers.computed is a TurboKartRacersComputed built by computeTurboKartRacers(raw) from src/computed/modes/turbokartracers.ts. All inputs are fields of the raw TurboKartRacersStats block (its maps record, its monthlyPoints record, its periods block of TurboKartRacersPeriodStats, and top-level counters).

Conventions used below:

Ratios are bare (not percentages), rounded to 2 decimals. When the denominator is 0 the numerator is returned as-is (K/D convention).
*Share fields are percentages from 0 to 100, rounded to 2 decimals; a zero whole yields 0.
Oscillating (monthly/weekly) fields pick the live A or B bucket for the current date at compute time. Monthly: bucket A when now.getMonth() % 2 === 1 (February, April, June, August, October, December), otherwise bucket B. Weekly: whole weeks elapsed since epoch 1417237200000; bucket A when that count is odd, otherwise B.

`TurboKartRacersComputed`

The top-level object at player.stats.turboKartRacers.computed. The derived inputs below are plays = sum(map.plays for each raw.maps entry) and trophies = raw.goldTrophies + raw.silverTrophies + raw.bronzeTrophies.

export interface TurboKartRacersComputed {
  readonly totalPlays: number;
  readonly winRate: number;
  readonly totalTrophies: number;
  readonly trophiesPerPlay: number;
  readonly goldTrophyShare: number;
  readonly lapsPerPlay: number;
  readonly boxPickupsPerLap: number;
  readonly coinsPickedUpPerGame: number;
  readonly netBananaHits: number;
  readonly bananaHitRatio: number;
  readonly blueTorpedoHitsPerPlay: number;
  readonly mostPlayedMap: string | null;
  readonly bestMonthlyPosition: number;
  readonly averageMonthlyPoints: number;
  readonly monthly: TurboKartRacersPeriodComputed;
  readonly weekly: TurboKartRacersPeriodComputed;
}

Field	Formula	Meaning
`totalPlays`	`sum(map.plays for each raw.maps entry)`	Total races played, summed across all maps
`winRate`	`raw.wins / totalPlays`	Fraction of races won (bare ratio, not a percentage)
`totalTrophies`	`raw.goldTrophies + raw.silverTrophies + raw.bronzeTrophies`	Lifetime trophies of all colors
`trophiesPerPlay`	`totalTrophies / totalPlays`	Average trophies (podium finishes) per race
`goldTrophyShare`	`100 * raw.goldTrophies / totalTrophies`	Percentage of all trophies that are gold (0-100)
`lapsPerPlay`	`raw.completedLaps / totalPlays`	Average completed laps per race
`boxPickupsPerLap`	`raw.boxPickups / raw.completedLaps`	Average item box pickups per completed lap
`coinsPickedUpPerGame`	`raw.coinsPickedUp / totalPlays`	Average coins picked up per race
`netBananaHits`	`raw.bananaHitsSent - raw.bananaHitsReceived`	Banana hits dealt minus banana hits suffered (can be negative)
`bananaHitRatio`	`raw.bananaHitsSent / raw.bananaHitsReceived`	Banana hits dealt per banana hit suffered
`blueTorpedoHitsPerPlay`	`raw.blueTorpedoHits / totalPlays`	Average blue torpedo hits per race
`mostPlayedMap`	`argMax(map id -> map.plays, floor 0)`	Key of the map with the most plays; `null` when no map has more than `0` plays
`bestMonthlyPosition`	`minPositive(month.position for each raw.monthlyPoints entry)`	Best (lowest strictly positive) monthly leaderboard position ever held; `0` when no positive position exists
`averageMonthlyPoints`	`sum(month.points) / count(months)` over `raw.monthlyPoints`	Average points per recorded month; when there are no months, the sum (`0`) is returned
`monthly`	`computePeriod(monthBucket(now) === "a" ? raw.periods.monthlyA : raw.periods.monthlyB)`	This month's period stats from the live oscillation bucket; see `TurboKartRacersPeriodComputed`
`weekly`	`computePeriod(weekBucket(now) === "a" ? raw.periods.weeklyA : raw.periods.weeklyB)`	This week's period stats from the live oscillation bucket; see `TurboKartRacersPeriodComputed`

`TurboKartRacersPeriodComputed`

The shape of both monthly and weekly. Built from whichever TurboKartRacersPeriodStats slot (monthlyA/monthlyB or weeklyA/weeklyB) is live for the current date; the first four fields are copied through unchanged.

export interface TurboKartRacersPeriodComputed {
  readonly boxPickups: number;
  readonly goldTrophies: number;
  readonly silverTrophies: number;
  readonly bronzeTrophies: number;
  readonly totalTrophies: number;
}

Field	Formula	Meaning
`boxPickups`	`period.boxPickups`	Item box pickups in the current period
`goldTrophies`	`period.goldTrophies`	Gold trophies earned in the current period
`silverTrophies`	`period.silverTrophies`	Silver trophies earned in the current period
`bronzeTrophies`	`period.bronzeTrophies`	Bronze trophies earned in the current period
`totalTrophies`	`period.goldTrophies + period.silverTrophies + period.bronzeTrophies`	All trophies earned in the current period
