I wonder if there isn't some simpler aproach that can give us 80% of the 
benefit with 20% of the effort and can be tested empirically.  For example 
safety stops for no stop dives can significantly reduce doppler scores.
Maybe something similar can be done for stop dives and then tested empiracly.
