BRM speaking, how many tables you play has nothing to do with it as far as adjusting. Skill speaking, you should be playing the amount of tables that you have the highest win rate on and are making the most per hour on. If you can make 5bb/100 playing 1 table, but you can also make that playing 5 tables, but you drop down to only 1bb/100 at 6 tables, then you should be playing 5 tables, because then you're making the most per hour. If you're making 5bb/100 playing 1 table, but then drop to 2bb/100 with two tables, then you'll be making more playing 1 table.
