Hi Dev - my (basic) understanding is that PVT doesn't just look at the VV engagement/health (though this is required for trauma/past healing), but that when this is functioning sufficiently well, it then needs the DV and/or SNS to engage with it (and be in regulation) to allow fuller healthy states.
So broadly VV (or 'social engagement system') + DV = healthy rest/pleasure (vs DV on its own = collapse etc); and VV + SNS = healthy excitement (vs SNS without VV = fight/flight etc).
DV + SNS without VV = Freeze, and I'm not sure what DV + SNS + VV equates to - probably a very funcational system with good range and variability?
