Default Oxygen regulator for MH EDS

I was using a nelson regulator and sent the entire O2D1 system back to mountain high a few years ago when they offered a free upgrade and checkout. Interestingly the found that the nelson regulator changed its output by more then 15 psi as the o2 bottle got low, and not they way you would think. It got higher as the pressure got lower. I had set it with a full bottle at 20Psi and was up to 30 psi at 500psi in the bottle.
