Assuming correct 4x raising strategy, there is the probability of each outcome, given a 4x raise:
Win: 58.82%
Loss: 38.47%
Tie: 2.72%
If we factor out the ties, the probability of winning is 60.46%. In 96 hands resolved, the expected number of 4x wins is 58.04. So, 66 wins is ahead of expectations, but not significantly.
This question is asked and discussed in my forum at Wizard of Vegas.
