That's very detailed but some of the numbers are strange. I can't imagine a coat, even a long reinforced coat, is going to take 10 rounds (while a non-reinforced coat is 5), and there are donning times for non-armors like AT 1 (it takes a base of six rounds and a minimum of two rounds to put on "no armor"... what happens if you don't have time for that?), 3 and 4.
After looking at the numbers, I would probably just say look at the maximum maneuver penalty. One round per -10, minimum one round. That's in the same general range, doesn't need a separate table, also handles piecemeal armor in RMU easily (if you only have time to put on parts).
