it runs at 800-900 because its unregulated co2. what you're really trying to ask is "whats the lowest it will recock consistently at while still shooting at maximum FPS?"

first, what kind of reg is it? second, what have you done to it (polishing internals, new internals, springs, etc.)? my imagine recocks at 250psi with stock valve, modded pin, CIP Assault Block and polished internals. how much airflow and resistance your internals get is a major part of your lowest psi setting. just turn it down until it wont recock, then start turning it up slightly (i do 25-50 psi at a time). walk the trigger and see if it recocks every time. if it doesnt, its being starved of air, and you need to turn it up some more.
