Edisto, We'll compare the before and after times on the controlled piece of oak with the same chain. The 460 was bought the last week of December and has been run four to five days a week since then. It is dead stock with no modifications. It is run on 93 oct pump gas with Stihl Ultra mix, no mm on this saw, just dead stock as it came from the dealer.
If you want to do a comparison, more cuts are better. 10 is a nice number of you have the wood for it.
Bigger spacing of the cuts (as opposed to 2 inch cookies) will help insure differences aren't due to differences in the wood, as the quality of wood is likely to be spatially correlated.
One thing I thought about recently, given that you can't alternate cuts when doing a before and after comparison, is blocking a cant with the saw for the before, and cutting the resulting pieces for the after. If the wood was thoroughly seasoned, this would be a good setup, but if not, it could actually be a bad idea, because cutting the wood into pieces would result in faster drying, making the comparison invalid.
I'd recommend video taping all of the cuts, so you can use the video to get good measurements. I typically make 3 measurements from a video, and average those.
Definitely a pain, but at least the results will have some meaning. Be glad to run the numbers for you when you get them.
Aside from the cut comparison, I have a cousin who is a 3rd gen logger, makes his every day living doing it. He has been doing it for close to 40 years, he falls oak and walnut everyday. He runs 440,460s' but his main weapon is a 660. He owns four of them, all are dead factory stock. I'm going to let him use the saw as well.
To be honest, I think that this will be a more valuable evaluation than the numbers.
Although his comments will be totally subjective, he isn't on AS, know none of the parties and his feed back will be as honest as humanly possible. If the saw impresses him you can bet your azz it is a runner, this man files some of the most wicked chains you've ever seen.
Any tool preference is subjective. Read one of the threads on the Fiskar's Super Splitter. Some love it, some hate it. A video isn't going to help that. I think your cousin is the kind of person we're going to want to hear from.
I like Simon's style personally. To be good at something, really good at something you have to be confident in your ability to the point of almost being arrogant. That's why I still bet on my shooting ability. I'll get your money 9 times out or 10, the one time I lose gives me a reason to laugh and practice more.
I like his style a lot, but I don't see the arrogance that others do. He just genuinely doesn't give a crap if you want him to work on your saw or not.
