The reason they give such good fills is because they are new to doing fills. They are a bit nervous about the entire thing so they are sure to check the pressure markings and the hydro and vis dates on every cylinder they fill. When they first began to do fills, they often gave very light fills. I remember in the begining one of my 3000psi tanks was only filled to 2100 psi. I think the divers made sure they figured out how to do it really quickly.
It is nice that they have the ability to do HP fills there, however they only have one HP fill whip.
