I agree with you, that multiple repetitive diving is also a good application for Nitrox, even for the first dive. That is sort of analogous to my classification of "long shallow" dives.
I would plan the Nitrox mix just like for a technical dive, by first determining the MOD, then the desired PO2, then by dividing the PO2 by the P(total) compute the FO2, giving the maximum beneficial mix for the multiple repetitive dives. Surface interval should wash out the CNS% accumulation, but that calculation should probably be run as well.
Alternatively, just sticking to EAN36 for dives to 100 ft or less also works well for these multiple repetitive dives.
Unless people are diving deeper than 100 ft, I do NOT understand why they are using EAN 32. I suppose it depends on where the bugs are hiding.
