IMO the only thing he was doing is comparing a couple of saws he had that were roughly the same cc's to see how close their cut times were. Neither his comparison nor any timed saw cut comparisons are very scientific because of the number of variables (saw tuning, pressure applied during cut, operator skill level, wood size, wood density, chain type, chain sharpness, etc.). Thats why I find it funny that someone across the country can say that my brand X saw is roughly X times faster because I raced it one time and got these times. More emphasis should be spent on sharpening techniques and chain maintenance rather than arguing which XXcc saw is faster. The benefit of having a better performing "out of the box" saw is negated if you don't know how to properly maintain your chain.
