Buh is well tested and verified model - VPM (in comparison) simply is not. Its being constantly tweaked so as it doesnt bend divers and in doing so is becoming increasingly - perhaps unsurprisingly, more and more like Buh
NO... that's wrong Mike.
VPM-B is the only revision, and this was released in Jan 2003. VPM-B has remained unchanged in this configuration since, and VPM-B is the most widely used bubble model 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. VPM-B/E satisfies this request. Not all divers want or need to use this much deco.
The history of VPM and some of its accomplishments are
listed here.

Added for OP. The VPM in your VR3, is not real VPM. It would appear to be some kind of approximation or emulation. Some report its output can be OK at times, but often its way off from your tablet plan.
The only computer available with real VPM-B and VPM-B/E installed, is the Liquivision X1 with V-Planner Live installed.
