HippoValkyrie 14

(attacks thrown ÷ attacks entitled) × 100, summed across every war we have verified attack data for in this window. A finished war whose roster shows this account was entitled and threw nothing counts as missed attacks -- that is a real no-show, and it is what every clan page already counts. A war we have neither attacks nor a finished roster for doesn't count either way -- it's absent, not a fabricated miss.

Every entitled attack in scope becomes one slot: a real outcome if thrown, "missed" if not. The breakdown is percentages of those slots, rounded so they sum to exactly 100 (largest-remainder method, not independent rounding per segment). Missed attacks drop out of the up/down/mirror breakdown since there's no opponent to say what they'd have been up against.

Same slot-and-rounding method as attack performance, from the defender's side: every real defense this account's base has on record this window, classified by stars conceded. Conceding 0, 1, or 2 stars all count as a successful defense -- only a 3-star is a real loss, which is why they share a green gradient here rather than four separate colors. A war where the base was never targeted doesn't count either way -- it wasn't tested, so it's left out of this rate entirely rather than padding it with an untested result.
