I am trying to switch from HiLo to Red 7. Something weird happens when I try to simulate playing 1 hand constantly and playing 2 hands at RC >= -1.

In the 1 hand case, the edge is positive at RC >= -8. However, it only positive at RC >= -3 when simulating the 2 hand case. Could anyone tell me why is it the case?
