Sorry if it's been said already but I am watching the Canada JR game and may have missed it, but nobody seems to have mentioned that winrates are very tough to get a handle on at the micros since your not usually at a stake long enough to get a significant sample. Depending on winrates you will move up with 20BI's (min I prefer 25). Here's something I posted a while ago.

You need 20BI's to play a level, that is 2000BB

you need 2000BB's to double your roll and move up and at $10NL you need 2500BB for $25NL



@1BB/100 x 200000 hands, move up

@2BB/100 x 100000 hands, move up

@3BB/100 x 66667 hands, move up

@4BB/100 x 50000 hands, move up

@5BB/100 x 40000 hands, move up

@6BB/100 x 33333 hands, move up

@7BB/100 x 28500 hands, move up

@8BB/100 x 25000 hands, move up

@9BB/100 x 22222 hands, move up

@10BB/100 x 20000 hands, move up
I personally don't think improving your hourly rate by playing more tables at the micros is necessary since your invariably going to bottom out on skill ahead of BR . Play quality hands, get a better winrate since it is such a short trip anyway.
