Tuning RTI Prophet Hammer Spring

Does anyone know how many options there are for different hammer spring weights/tensions?

I would assume there are different options for P1 and P2..correct? With the P2 using a lighter spring..less force to cock and because of less pop required to open the valve. And different springs for each of the standard non-adjustable regulators..125bar, 145bar, and 175bar..
 
The Performance models have an adjustment screw in the Extended Butt Stock. The Standard models have a hammer spring that is not adjustable due to Butt Stock being shorter and not having a hole for HS adjustment. Even if you take the Butt Stock off the standard model the only may to change HS tension is to swap springs.

So my thought was there are at least 3 springs..one tension for each standard regulator pressure.

Then maybe another tension for the new P2..since the valve needs less HS to operate.
