比的是谁：这场之前最近 5 / 10 / 20 场完整官方 9 或 18 洞，按场次算不按天数。不含这场本身，也不含同一天的另一场。Window: the last 5 / 10 / 20 complete official 9- or 18-hole rounds before this one — counted by rounds, not days. Excludes this round and any same-day round.

9 洞不跟 18 洞比总分：好差一律走「每洞相对标准杆」，再折算回这场的洞数说成几杆。9 vs 18: comparison always runs on strokes-over-par per hole, then converted back to this round's hole count.

球杆赚亏：净贡献 = 相对这场开打前滚动 12 个月的期望杆。「全场影响」= 每杆差 × 这场用了几杆，一杆也算数；样本够不够另用灰字标记说明，不删条目。Club gain/loss: strokes gained vs a 12-month rolling baseline as of this round. "Total" = per-shot delta × shots this round — a single shot still counts; sample-size caveats are shown as notes, never used to drop a row.

推杆只计次数，距离一律作废。练习场与挂起杆不进球杆账。各杆赚亏加总不等于这场的总杆差（基准不同，页面不做这个加总）。Putter counts only strokes, distances voided. Practice rounds and held shots stay out of club stats. Club gains do not sum to the round delta — different baselines, so no such total is shown.

球场难度校准（校准分 ｜ 原分）：页面所有净贡献默认用校准分，顶部导航行可切回原分。期望杆 E 仍是她自己的球位 × 距离表。校准差额 = 这场球场（这组 Tee）按 USGA Course Rating / Slope 换算的官方难度，相对她近一年（只看当场之前 365 天）打过的球场组合的差额；差额按权重 w 分摊到每一杆——主要压在开球与攻果岭，推杆固定只分 0.10。缺官方评级的场不校准（校准分 = 原分）并标「未校准」。主场熟悉度不属于球场难度，不在校准范围，仍留在分数里。场次徽标：Tee · CR/Slope · δ 每洞（δ 为正 = 比她常打的组合难，校准后往上补；为负 = 更容易，往下扣）。Course-difficulty calibration (Adjusted | Raw): every strokes-gained number defaults to the adjusted value; the toggle in the top nav switches back to raw. The expectation E is still her own lie × distance table. The adjustment = this course's official difficulty (this tee) via USGA Course Rating / Slope, relative to the mix of courses she played in the 365 days before the round; it is spread over shots by weight w — mostly tee shots and approaches, putts fixed at 0.10. Rounds without an official rating are left unadjusted (adjusted = raw) and labelled "not calibrated". Home-course familiarity is not course difficulty and stays in the score. Badge: Tee · CR/Slope · δ per hole (positive δ = harder than her usual mix, adjusted values lifted; negative = easier, trimmed). 球场难度校准：Claude Code · Claude Fable 5.1
