Your VPIP is way too high and your PFR is too low. I'm at about 19/14 or so, which means I am playing much tighter than you but I am raising many more hands preflop and limping / calling raises less.

Don't limp Axs hands without a few other limpers to make it worthwhile, same with suited connectors. And if I'm in the CO or button I raise with all hands that I want to play. It seems you are open limping way too much and only raising good hands.

Also, reads are overrated. Work on picking up on betting patterns instead. Reads help somewhat, but I do very well at 50nl and my reads on individual players are terrible and almost non existant. If a player stands out as a complete donkey is my exception.
