Hajimoto:
Not that my confirmation is required for your data to be relevant but thank you Scott for posting your findings as they mirror mine exactly. I will try my best to post any and all technical finding here in this thread in an attempt to consolidate the data.
I am thoroughly impressed with the consistency of these PCP's and your data does nothing but elevate my positive impression of the workmanship on these units.

If the factory continues to build the future units to these specs, there will be very little for end-users to complain about.

oldpro:
Short stiff spring all else bone stock. Ill tune it to 3 power levels with same spring.
