Hmmm... I prefer to be able to maintain neutral buoyancy all the way to the surface. And with less than 500 psi...

I always weight myself for 10' at 500psi. Depth wouldn't matter with a drysuit, and if I can comfortably hold the stop at 500psi, I can adjust my breathing to account for the 2 pounds difference below 500. Either way pretty much gives you the same results. It's not an exact science.
