I took PADI tec 40 and 45, and one thing that bothered me was following the run time, starting from the initial ascent, through the bottom time and during decompression. Basically, the run time forces you to stick to a strict schedule, putting stress on you during critical tasks such as gas switches. It never made sense how you're supposed to carefully check your gas and depth and do a switch at the same time you're rushing to meet the schedule planned by your run time.
Then I moved to IANTD normoxic, and my instructors did away with run time. This allowed us, in team diving, to do our gas switches sequentially, so you can check your teammates switches, and start your deco time only when everyone has switched. So you don't have to stick to an absolute run time schedule planned at the start of the dive. It also makes more sense, for instance, if you had to spend a bit more time during a switch, to untangle a hose, or fix a buoyancy problem, which would throw off your run time for the rest of the dive.
So I say, why task load yourself and stress out trying to stick to a run time schedule -- to the point where rushing can compromise safety?
