Insanely close 23.5 finish

My wife (51F) finished the workout Rx in 19:59. Needed to frame by frame the video to know.

Frame 1 rower reads 49 cal clock at 19:59

Frame 2 rower reads 50 cal, clock is literally in the process of changing but does not yet read 20:00

Frame 3 clock hits 20:00.

I have never seen it this close, just insane. It’s like milliseconds.
