Jacfin,

By my quick estimates:
Over 1000 bets
20 should be expected.
30 would be unlucky.

I would probably factor in a drawdown of 50 units.
So betting 1% of account, non-reducible on losing run should be very safe.
That is if the system holds up of course.

Sound about right?

Like Chrome suggested, I'll have $10 on each, but before betting decent amounts I'll monitor for another 250 bets.
