How does it feel when you cock it? I don't know the official answer for you but the cocking pin should not be bottomed out at the bottom of the cocking ramp. Maybe .020 to .040 from the bottom. The shorter the spring setting, the more you cock... or over cock it.

You can go closer to the bottom but do not let the cocking pin hit the bottom of the ramp when firing. It should wiggle a little side to side before you put the BAS back in.
