All that testing is boring and a lot of work for nothing but putting builders work against each other or selling one to buy another guys work cause it was .2 faster. Rim size might make a difference but the strongest saw will still win if they can setup a chain for it. Stock chains normally don’t really show the best way. One guys saw with a 7 pin cutting at max torque output can cut the same speed overall as a saw with a 9 taking smaller bites.
Race in some square wood and have fun. You guys say you do t race saws but all that testing is racing still[emoji2359]
