@@ChainsawUsers This is part of the reason I got the FG3. I was attempting to see where we cross over the point of benefit of adding top plate cutting angle and was struggling to keep the file in the right place to change it by 5 degrees each time. Hopefully I'll get to try a few things again in the next couple of weeks. I tried last week but it was snowing and I lost interest in freezing to death while doing it. Previous attempts with tilt I saw a 7-19% difference depending on the chain and wood but really want to look into it more because the results were too varied. C85 showed the biggest change

I still think it's for simplicity. The majority of people stuff it up anyway so it's just easier to say hold it flat. When some new to saws that asks me what to use, I just recommend semi chisel and a 2 in 1 guide. This is a little more advanced for when people are looking for every bit of chain performance they can find.

It's dragging against the back of the depth gauge with no pressure on it, it's not hurting anything
