true though. It's a good idea to have a 200-400psi differential between the HPR and the tank reg to help prevent shootdown, especially if you don't have a high flow tank reg. However, with regs with really good flow this, kinda, goes out the window (see Ninja SLP). I think as a general rule of thumb (for all markers), it still holds true, but there are some specific cases where it doesn't apply.
