Actually Verhoeven looked at this in his paper. He found that even if you short-circuited the progression the higher grits would eventually produce the exact same edge they would had you gone up normally. It took more than 1 or 2 laps to do it, for obvious reasons, but once the two edges were equivalently sharp there was no way to tell which one had been taken up the progression and which one had gone straight from 2000 to CrOx.
