Theoretically, it could be the case; practically, I think there is too much variability between individual guns, gas port sizes, conditions of extractors/springs etc to make general guesses. My midlength 14.5 BCM upper went through 1600 rounds of Wolf and 200 rounds of S&B ammo during 2 day Magpul class with one stoppage that had nothing to do with a buffer. That rifle has a F/A carrier and H buffer.
