All part of the risk...
Most counters, myself included, will overbet their BR and go bust somewhere along the line in one or 2 brutal sessions. Guys like Frank just continually bleed themselves dry.... My BR was built up from card counting and poker, then I foolishly bet 10 kellys per in a +6 tc shoe. Lost 10 of 13 hands, tied the other 3, (2 by taking insurance). I think Frank was standing next to me on one of thewm because I'll be damned if i didn't double 11 vs. 9 at about +19 running with $150 in the circle and have an ace drop on me. Plus, many counters do not practice enough to gain a significant edge, again, probably myself included, and will at times get jaded into overbetting by seeing morons splitting 5's versus an 8 with $500 out, getting two stiffs, and having the dealer bust after you hit your 12. Happens to the best of us.
