This is a rough estimate:

At four 2/4 tables I get about 250 hands/hr, so let's say you get the same for 1/2. I think about 60-70% of the hands at 1/2 are raked, so that's about 150 raked hands/hr. For a 10x bonus each raked hand is worth ten cents, so you'll clear it at about $15/hr, or in roughly 13 hours of four tabling.
