The QTC concept needs further explanation.

You have previously stated that you use a modified Level 3 count and further benefit can be obtained by tracking and taking advantage of the remaining deck composition. As Hi-lo, one of the easiest and most common counts that uses only three tags it is clear that deck composition can vary wildly at any given running/ true count but the system works because the Hi-Lo true count closely corresponds with the actual (dis)advantage. To take this scenario and compare it with what a Level 3 count already produces requires simulation to quantify any additional benefit and that’s what’s missing. Empirical evidence is not enough – you may just have been lucky but a large simulation can be achieved quickly with a modern computer producing a win rate and SCORE that can then be compared with the results of your count system.

In addition, to do all this with ramping variations, etc, almost extends to the limit of human capabilities and would need years of training to carry out successfully under the radar against many different rule sets in an actual casino environment.
