Summary statistics like mean 50m time move around with weather, fatigue, and gap-days — they carry too much noise to be a reliable longitudinal anchor. Specific reps within a set, like the final rep as a finish marker or the fourth rep as the first fatigue dip, are the durable observations worth naming. They isolate the same athlete at the same conditioning moment, so movement in those numbers is real signal rather than context drift.
