If anyone overfilled my HP tank by 500+ PSI I would be seriously pissed off. When I take my 119 to a dive shop they have tubs of water they put the tanks in to prevent hot fills. Plus, unless there is a lens between your tank and the sun and it' 125 degrees outside, there is no way you will burn off 500+ psi. If I'm filling your tank you'll be lucky if I give you a 2000psi fill. It's only fair to every other diver on the boat. It sounds like the less time you spend in the water, the safer everyone else is.
If you use all of a HP 119 or 130 then you're either breathing too hard or not considering every other diver on the boat and risk not being able to do a 4th dive.
I've never heard of anyone overfilling a tank by 500+ unless it's specified in the first year of it's first hydro, and that's only for LP tanks.
