The rake must hit $.25 to count I believe (from my experience). Absolute rakes in increments of $.05 at .5/1, so the pot has to reach $5 to count.

2/4 is by far the fastest clearing level. The rake is gigantic if you plan to play for pokerwinnings, but for clearing bonus it's godly. $5 pots are raked, which is basically every hand that sees a flop at 2/4. I play 6max 2/4 at absolute combined with rakeback -- I find it fairly awesome.
