I also started learning PLO two months ago, if its of any help here are my stats from those zoom games
I have no idea how I managed to drop that much at PLO10Zoom, and feel quite embarrassed about it. PLO2 and PLO5 felt very soft, but at PLO10 there were already noticeably less fish though. I don't doubt that PLO10 wouldn't be beatable and for the small sample I played at the lower stakes I would say that they are very easily beatable.
I did really enjoy playing Zoom, had difficulties reading the board and many times made mistakes that cost me a stack but PLO5 is very forgiving about that. Was on heavy meds, and with little sleep, but still managed to keep a winrate at PLO5 - so if you aren't doing this to make money I do think micro zoom is a great place to start learning. You get so many hands with zoom, and its fun too.
Right now I'm playing PLO25 at regular tables.
