I am a terrible tester and can't count higher than 3 or 4 pints.
I picked 200 or 400 strokes out of a hat. No idea what the actual number it.
But it has been my experience that when a plane is sharp it largely doesn't matter what it is but as they dull my bedrocks eventually start chattering and stuttering and tearing out (the iron after all is left by a tensioned leaf spring) but my infills planes just take more work to push. Which means that since I am not good at sharpening before I need to, with a bedrock I find I get a poorer surface and maybe a little tearout and I have to stop and switch blade/sharpen. With my infill planes I just realize that the plane seems harder to push - at which time I sharpen or swap irons - but there is no damage to the work to be planes out later.
