I mentioned this in someone elses blog and I'll say it here also because I think it's just such a damn good idea. You're almost doing it anyway - consider some of your 2-tabling 6max sessions study sessions. Don't try to run up hundreds or thousands of hands, but maybe do a 30 minute session and try to extract the maximum lessons from it. You could easily do one of those every day and just think about every range and sub-range for every action for every player on the table(s), call it part of your study time and then have your "playing" time on the FR tables.

But make them short and focused is my point. Ok, interesting hands might not occur - does that really matter? Everyone is on about how important it is to get the maximum out of small pots. And keeping the session short means that focus should not falter. In that way they become actual learning sessions instead of just swongy -EV play sessions on a structure you're not comfortable with.
