I'm guilty of confusing you here. Sorry. I don't know what a Doppler model is. The Buelhmann models and the DCIEM models were refined using Doppler testing, but that's different than what I'm talking about. What I use is an RGBM model. I test myself post dive with a Doppler.
I didn't say what I dive is more or less conservative than neo-Haldanean models. BTW, "conservative" doesn't automatically mean having a shorter NDL. Other factors, like ascent rates, come into play. I said that computers are built to be conservative. This is done 1) to counteract the inherent compound errors of the respective models over multiple dives and 2) account for people who have predispositions to bubbling-weight, age, physical conditioning, dehydration, PFO's, etc.
As for how I dive, since I Doppler check myself against a particular schedule, I get a pretty good sense for how my body behaves relative to that schedule-on average. I also know to back-off when I'm tired, cold, sleep deprived or just having a bad day. As such, I listen to my body as much as any particular schedule.
