Hourly Rate Calculation ... NLTRN

[TheSalche]

So I'm making the switch to HUSnGs on FTP and so far its going well ... 75 tournies into it I've got a 13% ROI and I decided to do some money calculations ...

60 mins / 5 mins per match * 2 tabling = 24 matches/hour
$6.25*.14*24 = $21/hour.

I added in an extra 1% from RB. That hourly rate seems a bit high for the micro-stakes I'm playing, is my 5 mins/match too low of a number? Is this ROI sustainable at this level of play? Anybody else care to share their experience with this level?

Thanks in advance! I plan on posting here for a while now =).
