Special-award rate 17.8%; combined 43.6%.专项奖率 17.8%；合并口径 43.6%。
These tier counts exclude 2025, whose award text is missing from the official database. The award-winning projects listed below do include 2025, recovered from the grand-award press release, so the two will not add up.层级分布剔除了 2025 年——该年官方库缺奖项文本。下方的获奖作品清单则包含 2025 年（从大奖新闻稿补回），因此两处数字不会相等。
The gap from the all-track rate of 30.3% is not statistically significant (Fisher exact p = 0.158).与全赛道 30.3% 的差距不具统计显著性（Fisher 精确检验 p = 0.158）。
