Blitz Survival Games computed stats

Derived Blitz Survival Games metrics, attached as the always-on computed property of the raw stats block: whenever player.stats.blitz is present, player.stats.blitz.computed is a BlitzComputed built by computeBlitz(raw) from src/computed/modes/blitz.ts. All inputs are fields of the raw BlitzStats block and its kits record of BlitzCombatStats.

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.
• *ForNext* fields are the additional amount of the numerator stat needed to reach the next whole ratio (floor(num / den) + 1); 0 when the denominator is 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.

BlitzComputed

The top-level object at player.stats.blitz.computed. The win-share denominator is modeWins = raw.winsSoloNormal + raw.winsSoloChaos + raw.winsTeamsNormal.

}

Field	Formula	Meaning
kdr	raw.kills / raw.deaths	Overall kill/death ratio
killsForNextKdr	neededForNextWholeRatio(raw.kills, raw.deaths)	Kills still needed to reach the next whole-number KDR
bowAccuracy	raw.arrowsHit / raw.arrowsFired	Fraction of arrows fired that hit (bare ratio, not a percentage)
damageRatio	raw.damage / raw.damageTaken	Damage dealt per point of damage taken
avgGameDuration	raw.timePlayed / raw.gamesPlayed	Average time played per game (same unit as the raw timePlayed counter)
damagePerGame	raw.damage / raw.gamesPlayed	Average damage dealt per game
chestsPerGame	raw.chestsOpened / raw.gamesPlayed	Average chests opened per game
potionsPerGame	raw.potionsDrunk / raw.gamesPlayed	Average potions drunk per game
tauntKillRate	raw.tauntKills / raw.kills	Fraction of kills scored while taunting (bare ratio)
soloWinShare	100 * (raw.winsSoloNormal + raw.winsSoloChaos) / modeWins	Percentage of mode wins earned in solo queues, normal plus chaos (0-100)
teamWinShare	100 * raw.winsTeamsNormal / modeWins	Percentage of mode wins earned in teams (0-100)
monthlyKills	monthlyValue(raw.monthlyKillsA, raw.monthlyKillsB, now)	Kills this month, from the live monthly oscillation bucket
weeklyKills	weeklyValue(raw.weeklyKillsA, raw.weeklyKillsB, now)	Kills this week, from the live weekly oscillation bucket
mostPlayedKit	argMax(kit id -> kit.gamesPlayed, floor 0)	Key of the kit with the most games played; null when no kit has more than 0 games
kits	one entry per key of raw.kits	Per-kit breakdown, same keys as the raw record; see BlitzKitComputed

BlitzKitComputed

One entry per key of raw.kits, computed from that kit's BlitzCombatStats. The kit's losses are derived first: losses = max(0, kit.gamesPlayed - kit.wins).

export interface BlitzKitComputed {
  readonly losses: number;
  readonly wlr: number;
  readonly winRate: number;
  readonly killsPerGame: number;
  readonly bowAccuracy: number;
}

Field	Formula	Meaning
losses	max(0, kit.gamesPlayed - kit.wins)	Derived losses with this kit (games played minus wins, never below 0)
wlr	kit.wins / losses	Win/loss ratio with this kit
winRate	kit.wins / kit.gamesPlayed	Fraction of this kit's games won (bare ratio, not a percentage)
killsPerGame	kit.kills / kit.gamesPlayed	Average kills per game with this kit
bowAccuracy	kit.arrowsHit / kit.arrowsFired	Fraction of arrows fired with this kit that hit (bare ratio)
