Each commit was counted once per language in the repo regardless of that language's share, so Shell (present in many repos as small deploy scripts) appeared larger than Rust. Now weights each commit by the language's byte proportion in the repo (e.g. a commit to a 95% Rust / 5% Shell repo contributes 0.95 to Rust, 0.05 to Shell).
