Non-author timings exist for several systems but live in only four kinds of place: a benchmark's efficiency table (WorldRoamBench v5 times 10 open models on one H20), an efficiency paper's baseline row (QuantWM v3 times LingBot-World-v2 and HY-World 1.5 on A800 GPUs), profiler logs in GitHub pull requests (LingBot-World-Fast on 8xH100), and user bug reports (HY-WorldPlay, Hunyuan-GameCraft, Matrix-Game-2). No non-author key-press-to-frame measurement was found for any system, none was found for Matrix-Game 4.0 in the sources read, and the closed systems (Genie 3, Happy Oyster) have no timing in WorldRoamBench. WorldMark's 'latency' is an in-video response metric, not wall-clock time.

Curator qualifications: Non-author timings live in four places: a benchmark efficiency table, an efficiency paper baseline, PR profiler logs, user bug reports.

Evidence claims:
- [sourced_fact] Non-author timings exist for several systems but live in only four kinds of place: a benchmark's efficiency table (WorldRoamBench v5 times 10 open models on one H20), an efficiency paper's baseline row (QuantWM v3 times LingBot-World-v2 and HY-World 1.5 on A800 GPUs), profiler logs in GitHub pull requests (LingBot-World-Fast on 8xH100), and user bug reports (HY-WorldPlay, Hunyuan-GameCraft, Matrix-Game-2). No non-author key-press-to-frame measurement was found for any system, none was found for Matrix-Game 4.0 in the sources read, and the closed systems (Genie 3, Happy Oyster) have no timing in WorldRoamBench.
