You're playing all the simple situations right but it looks like maybe you are too inclined to fold in marginal spots. Obviously this is one of the cons involved in 12-16 tabling so I don't know how much you can do about that if you're dedicated to keeping that volume. Your opponents are being more aggressive than you on later streets and taking advantage of your handicap so you might want to drop to 6 tables for a while and have someone with a better red line sweat you and make some suggestions, at least some of which should be scalable to your preferred MT ratio.
^ That is what magic red line 8 ball said when I showed it your graph.
Would you have considered this a good month if you ran at EV? Then don't change anything.
my recommendation, cut your tables in half. really- 6 to 8 tables. then double the amount of hours you play and treat poker like a job. 48k hands 12-16 tabling is not that many hours. i am having the same problem. finally, make sure you are studying well, and watch vids.
also ur ev adjusted winrate is not that miserable for 2-4. but ur redline makes me think ur hourly will in fact go up dropping tables
my redline very mediocre but my thoughts on it are
your not valuebetting thin enough
your b/f too much
you'd rather win at showdown than make spewy calls
and lastly, yes your probably not getting aggressive enough and trying to move people off their hands.
Let's hate on a serious reply because it ended with a smart-ass line of completely contradictory advice and that was the only part we bothered to read. It's all one big level in here.
