If you cant answer those questions after playing 700 questions with him, cut back on tables and really pay attention to how people are playing hands and take tons of notes.
That, or, and this is what i tend to do.
If we dont have the time/concentration/knowladge, of taking the right notes at the right time, then dont.
This might sound bad, but i know that playing 6-9 tables its gonna be super hard focussing on your own play + the play of villains.
And for regs it doesnt matter, because regs we will be playing whole the time against, so what i tend to do.
Is when i quit a session, is do a session review, and not only my own hands, but also interesting hands that have been played between other players, and then you have the time to take as long as you want to get reads and make notes. THIS only applys on regs though, because regs are gonna be there all the time, fish tend to bust and leave and you never see them again, so while playing, focus more to get reads on the fish because you will need them in game.
Make reads on the regs also, but if you cant find the time ingame, make those reads in your post session reviews,and use them the next session ingame
Also playing less tables helps making notes and getting reads, but if you want to be able to play a lot of tables and still make reads and notes, this is the best way to go i think, just becaus eeven the best of the best cant make notes while 20 tabling, becuase you just dont have the time...
