150% of your highest bet per hour
According to the books I've read, written by proported professional counters, you can expect to win 150% of yous largest bet, per hour. The general suggestion is to never risk more that 1% of your total bankroll on a single hand. Therefore:
$100,000 bankroll, largest bet $1000, expected return $1,500 per hour
$10,000 $100 $150 per hour
$1,000 $10 $15 per hour
This rate of return is of course contingent upon perfect basic strategy for the specific game you are playing, most apropriate betting spreed based on a perfect count, and, the 18 or so basic strategy adjustments to make, based on a completely accurate count. Oh yes, in the long run, also.
Additionally, this answer is also contingent upon my accurate understanding of what I have read. It did sound plausible. Hope it's right.
