Not sure which count you use, but if you're using a balanced count, you include the deck estimation drill too, right?

I follow a similar SOP re CVBJ drills before I enter a store, so to me it sounds like you are doing things the right way. All you can do is contine to play the right way and wait for the math to work itself out. It will as long as you continue to play the right way...hang in there.
