The bubble models take all relevent factors into account. The reason you don't see any programs out there is liability. The idea of generating tables that require deeper stops *AND* get you out of the water in less time is a liability nightmare, mostly because it goes against such strongly rooted conventional wisdom. I think that simple modifications of ascent profiles are sufficient. I can feel confident preaching deep stops without fear of liability issues, because if I ever get dragged into court, all my lawyer has to say is "WHAT? You took decompression advice from a fish nerd, who obviously knows nothing about decompression????

It's easy enough just to modify your ascent pofile to include deep safety stops. If you work those into your method of calculating tables (automatic if you have a dive computer, a simple multi-level dive for most desktop software), then you get a few extra minutes on the shallow stops, which is a good safety margin (even though you could probably *shorten* the shallow stops). The point is, you'll probably feel MUCH better after the dive.
