Fair enough......
As you can see by the discussion so far it is very difficult to get any sort of answer that you can base your deco on.
The interesting part of it all is had I only had the one computer be it BUH or VPM, I would have followed it and would only have padded the stops if it appeared to vary from my original dive plan and not questioned it.
It was only when I took the 2 computers with different deco software that I nearly shit myself when one wanted me to stay on the last stop for an additional hour.
Still not convinced.......But not bent either!!!

lol! I know how you feel Im often sat at 6m deco station bar in the same situation looking at the conflicting TTS and enjoying the 'chicken bone' and 'empty beer can' shower as my buddies on boat above enjoy the afternoon BBQ
I think both VR3 versions are conservative but if in doubt I guess you can do half the difference seeing as (for reasonable depth time dives) its only really the last few stops that are signif longer ones between the two.
My 'guess' (and it is an uneducated guess so likely bollocks) is that the vr3buh is on one hand penalising you for the slower ascent (due to deeper and more deep stops) and at same time not accounting for the benefit derived from those deep stops - hence the penalty its giving you. Be interesting to see how TTS changes if at all on vr3buh if you follow or dont follow vmpvr3 deep stops
