I don't really like Treantmonk's calculations, he assumes too many combats, too few short rests, and doesn't really optimize the builds at all. I do really love the way he presents things and shows all his assumptions and math though, many times I'll still learn something
D4 Deep Dive calculations are much better if you want to do optimized builds for damage.
My issue is the opposite. He assumes too few combats and too many rests. My primary game has about 3 combats per short rest, and almost never any long rests (West marches, so always ends each session back at the base).
As he says himself in his recent video, ever table is different, and he needs to focus on the feedback from the majority of his viewer polls.
I play almost exclusively online, including several multi-DM west marches campaigns, so have seen easily 50+ DMs over the life of 5e. Every single one is a little different when it comes to frequency of combat and rests, but I have never seen any that allow a short rest between every combat (without serious consequences at least).
