All the bets should be expressed in units. The result will be s.d. in units. If you express in dollars, the result, as in all the Chapter 10 charts, will be in dollars. But you still wouldn't be dividing by an average bet size.

You do divide by average bet to express everything in average bet units. The difference is the way you are telling the OP to do it he does that division many times. If you use the units you want to end up with, in this case average bet, you can either recalculate all your data to be expressed in average bets, or you can divide the existing data's SD expressed in dollars by average bet to get the SD expressed in average bet. To me, using a hand calculator, it is easier to divide by average bet once at the end rather than every data point by average bet to express it in average bet units before using it in the formula and then use it in the formula. But if I am writing a program to do it there is little difference in the work required for either method of getting the answer expressed in particular units. Obviously the OP is using a hand calculator, so I advised what is best for him.
I find a lot of MY confusion comes about because the math can be done using terms that can be in three different forms: percentages, units, or dollars. A lot of head scratching could have been avoided if I had double checked that all of my terms are in the same form.
I ran some CVData sims looking at a single card in a six deck game one card at a time. Then I ran a normal CVCX sim looking at the regular cumulative data that we're all used to.
Why is the cumulative standard deviation so much higher than a single card standard deviation?

Here's the sims of the single CARD 262 and then the regular old sim that spans 1-262.

Hopefully the resolution is acceptable. I'll repost the screenshots separately if not.

To Don and Ferenc11. Both screen shots of the RC breakdown are truncated. The left one just shows the negative EV TCs but does show the first advantage bet before things get cut off. That bet is 20 units with what looks like a 30 unit bet cut in half in the second advantage bin. To Ferenc11, the EV of that game on the left is $148/hour and a SCORE of 77.77, which is not negative EV.
