The ASP/USRPT 425s format looks simple but its discipline is brutal: same target time every single rep, ±0.2 seconds, 15–30s rest, 20–30 rounds. Hitting 13.0, 12.9, 13.1, 12.8 isn't a good set — it's inconsistency. The set only 'starts working' when you can hold the target across all rounds. And if every rep feels easy, you drop the target. Sean frames it directly: if you're not failing, you're not stressing enough.
