But when playing multiple hands, the total bet out is lower. My example was 10 units out on one hand after the shuffle, going to 2 hands with 2 units each(4 units total) when the count went negative. Once the count was positive, the extra hand was pulled down and the single hand was increased to 10+ units.
This opposite to starting out with a single hand, small bet and playing multiple hands with a positive count. Ken Uston/John May was pointing out that multiple hands dilute the advantage during positive count, but camouflages bet spread. So, if there is no heat, then playing one hand at the maximum bet versus the count generates the best return.
