Look, speed shows you know the drill. A two minute check is just going through the motions. If you can spot the big problems fast, that's real skill. That tiny cut probably wouldn't have failed on that dive anyway. Sometimes being quick and confident is better than being slow and overthinking every little thing.
Huh, so do you do your checks by feel or by sight? Because with that tiny cut you missed, you'd catch that by running the hose through your fingers nice and slow, not just eyeballing it. I learned the hard way after a buddy's inflator hose let go at 60 feet because I rushed and didn't feel the little nick near the fitting. A full two minutes is about pressure too, not just looking for cuts, you gotta let your gauges settle and listen for that hiss. Doing it fast might look cool on the dock but it's not worth the headache of a problem underwater.
