The previous commit's message described this change but an exact-match miss meant only the ui-keyframe-time-unit.md half landed. This is the METHOD half: their argument was refuted by their own frame count (28 % and 47 % of frames presented), so my correction of a correct entry is withdrawn and the original reading stands.
