Just because you don't see the chrome peel doesn't mean your cutter isn't sharp.I hear you it's not so much the guides and angles for me it's like When you said what are you looking for at the end result it's like I get there and I feel like it's not sharp enough and I go a bit more than I have a rip and hook What I should do is is take it Layer by layer Sharpen a bit then cut and sharpen then cut.. Another thing I'm hung up on is I can get my my tooth looking How it's supposed to on on round full chisel But sometimes you don't pick up a burr.. On the top plate but yet You're hook and gullet are perfect So I'm like am I done but I never got a burr on the top plate.. So I'm back-and-forth with myself about a clean edge on the top plate and I keep going pulling back, and now I ruined my hook.. So yeah I can file but it's the end result what I'm looking for knowing when I see it. And the same thing with semi chisel, I know the point isn't supposed to come together like full chisel but still, knowing What the point comes to, what it's supposed to look like on semi chisel Is a little tricky for me.
Get a new chain and keep it beside you when you file(same for the semi-chisel), and then make the used one look similar. It won't look exact, put it will give you an idea of how it should look. When it looks similar, go out and cut with it and see how it feels.
The fact that you are paying attention to it tells me you are on the right path to figuring it out.
