- 选一届和往届（或另一届）比，两边都至少 20 人做过的题才比；分比往届差 / 差不多 / 比往届好三组，一题一根哑铃条
- 侧栏「历年概况」改回「年度趋势」，地址换成 /admin/problem/trend

- * 历年概况（原「年度趋势」，设计稿「卡点与趋势」页的定稿 TrendFinal）：一个学年一列。
+ * 年度趋势（设计稿「卡点与趋势」页的 TrendB）：选一届，和往届（或另一届）在两边都做过的题上
+ * 逐题比「一次就对」，比往届差的排前面。
  *
- * 学年从 9 月 1 日算起（原来按自然年切，一个学年被切成两半）。进行中的学年只有几个月，
- * 拿它和整年比没有意义，所以旁边并排一列「去年同期」。单道题的历年变化挪进了卡点分析的右栏。
- * 口径（人 × 题、一次就对、做对之前交了几次）见后端 routes/admin/analytics.ts。
+ * 按届（班号前两位）比而不是按自然年：一个学年里同时有两三届在做题，按年切会把它们搅在一起。
+ * 往届是把更早几届的人合在一起算（人多的届分量大），不是几个百分比再平均。
+ * 比输赢按显示出来的整数百分比，差 2 个点以内算差不多。
