Personally for me I use this for birch plywood. 1/4” and up. I run 0.158” depth of cut with 75I MP feed. Thing last forever. I set my Z on the wasteboard so that it never cuts below Z 0. That’s just me Thought. If I’m cutting all the way through I don’t care what the actual thickness is and this way I don’t have to measure the stock. What I’ve found with compression bits is you have to go at least the diameter in depth of cut otherwise you won’t engage the downcut portion and you’ll get tear out on the top.
