I just want to get others opinions and through their experience what the best pressure switch safety settings for subcrital dx co2. In my experience the high pressure setting cuts out at approx 550psi and cuts back in at 450psi and the low pressure cuts out at 100psi and cuts in at 200psi.

In round numbers those look ok

Is there a reason you are using an auto-reset high pressure control? If there is a high pressure problem present why would you want the system short cycling on the safety control. Those (auto reset) controls are great for fan cycling but not recommended for a safety cut-out.
