I think there are good arguments for getting the recoveries down shorter than the reps. First off, as a marathon predictor Yassos tend to be a bit optimistic (for most people, but it obviously varies). Also, forgetting Yasso for a moment, 800 reps are good for improving aerobic capacity, and the shorter you can get the recoveries, the higher proportion of time you're working at/close to VO2 max. We tend to do 8/10 x 800 with 200m recovery on the track, which is not strictly timed but tends to be ~ 2 mins with a slow walk/jog recovery.
It can be difficult if there are a few runners of varying pace since the faster ones will get longer recovery. You can always improvise with some runners doing fewer reps, or throwing in the odd 600, etc.
