Yeh man, I know.
The other issue then is -- and I'm talking about how the computer works, not the actual human diver, of course -- that on a no-stop dive the fastest tissue compartment is taken care of by slow ascent rate and it doesn't really matter anyway except on a very short bounce dive. It will be a slower compartment that's controlling, in ZH-L16 they've 8, 12.5, 18.5, etc. minute half times. I've no idea how much delta-pressure it has to lose in order to make a difference to surfacing GF, nor which was controlling on that particular dive, but I would not expect to see any drop in surfacing GF until after at least a 3-4 minute stop. Ascent won't cut it unless you're so slow your leading compartment is off-gassing faster than the ambient pressure's going down. I doubt 40' in 7 minutes is slow enough even for the 8-minute TC.
