I don't think you can do it quite your way. I think you need to start two tables, side-by-side, one with a 4/6 cut and one with a 5/6 cut (or whatever comparison you want to make).

Then, you have to time how long it takes to deal each shoe and how long it takes to shuffle. Then, you can calculate how many hands per hour each table generates and what the short-fall is for the more poorly cut shoe.

Your analysis mentions one minute for an ASM, but it is clearly longer than that for hand shuffling. and, your analysis doesn't factor in the dealing time, which you need.
