I've just started using StoxEV and I'm just having a little trouble understanding something. I have made a simulation to show the EV of cold 4betting vs various ranges. I wanted to see the EV of 4betting with different hands, because I figured that holding blockers would increase the EV due to card removal.
If I set the 4bet range to ATo only, it shows that it has an EV of $2.29.
If I then add 22 to the range, it shows that the EV of 22 is $.66 and the EV of ATo has changed to $1.38, with the total EV being the sum of these two numbers ($2.04).
I cannot see how adding 22 to the range would decrease the EV of ATo. Shouldn't the EV of ATo stay the same? And if the EV of 22 is different to that of ATo, then the total EV of the hand should be the average of the EVs of the two hands, rather than the sum of those numbers?
