What I meant is, say there's pretty much exactly 2.75 cards in the tray, you should know the TC based on BOTH divisors (3, and 3.5)
Say RC = 27, then TC would be 9 and 7, respectively.
In my mind, that's an 8.
However, it's rare the the half-deck different divisor will produce a TC different by more than 1 so I doubt the increased accuracy of this method is more than negligible
