@kdhcpeace When I was racing, our maximum stroke rate on the water would be 30, when we were at full chat racing over 2000m.
Training on the ergo we would be anywhere from 18-30 depending on what we were training for, distance and so on.
If you're going over 32spm for any sort of time or distance, I'd look at the resistance of your machine and your technique.
From the start position, arms locked out straight and a straight back tilted forward, make sure your legs are done driving before you first lean back, then pull with your arms.
Then straighten your arms and let your hands get past your knees before you go back up the slide - you shouldn't be lifting the handle over your knees as you go forward.
This is mainly because on the water you'd be digging your blade into the water and possibly causing your boat to flip over - when you see people doing ergo world records and stuff they don't stick to this but doing it will help you get a good technique.
If you're doing this technique and you're still managing 30spm+ over a distance of 2000m or more, you're either a freak and need to join a rowing club, or your resistance is too low. 30spm for any length of time HURTS. They used to make us do it side-by-side, and the first one to black out and fall off their ergo was the loser.
