Neither is VPMB or VPM BE, none of them bare any resemblance to the original VPM!
Wrong again Mike....
VPM-B is just one single change to a single function, and this gives an ascent that has more curve to it. All the same science and gas properties are within VPM-B as VPM. The VPM-B revision was done by Eric Baker and Erik Maiken - two of the same group that gave us the original implementation. All models evolve and are revised. VPM was revised just once in 2003 to the current VPM-B in use today.

The VPM-B/E design is one of convenience. Some divers wanted a "best of both worlds" approach, that is: all the deep stops from a bubble model, combined with all the shallow stops of a Bulhmann style plan.
Exactly, deep/freq divers found the model not to work well so it was 'tweaked' to closer to Buh.....which was my point yes?
Is there anyone left who really dives a pure Bulhmann plan? And I mean real raw Bulhmann.... not the padded up versions in computers and software. Answer... NO. Those who use a Bulhman based plan will pad it with GF or Pyle stops, or both. So kindly Mike, stop trying to make us all feel guilty about VPM-B/E. Many divers are using a hybrid plan now, they do it for extra safety and comfort, and any time additional prudence is required. And that is good practice.
