I love zoom as a format, the level playing field in terms of bumhunting/table selection and constant action, but there are a couple of threads on 2p2 that make pretty depressing reading for anyone trying to grind a consistent profit. They show charts comparing the players with most hands at stakes 25-200 PL, and they show a sizeable difference between winrates at zoom and reg tables, to the point where it seems like there are hardly any winners at 50/100/200 over a decent sample. Rake really is huge.

Lots of people on this site grind zoom, including RIO pros which surely means at least some must be beating zoom games for a decent clip - not everyone can be losing over a big sample, right? I don't know how accurate the data on 2p2 is, but it just seems a bit pointless trying to grind up through the stakes at zoom if the rake is unbeatable for all but the biggest crushers. What are people's experiences with long run winrates at small stakes zoom?
