No worries Allan,
There are generally 2 ways you can tune your DM, either for efficiency, or for smoothness & softness on the ball.
If you want a smooth low kick shot that is gentle to the ball (what I highly recommend in the current crap weather) then:
Raise your dell to 20-22 and turn your LPR all the way in. Turn your LPR back out 3 full turns and check the bolt cycles properly. If it does, try winding the LPR in some more until you reach the point where bolt does not cycle properly (it may stick forward or slow half way through its cycle). Once you have found the limit of where the bolt cycles properly, wind the LPR back out by 1/6 of a turn and it should be just fine there. Adjust velocity via the HPR
If you want efficiency:
Lower your dwell to 17. Turn your LPR all the way in. Wind it out until the bolt cycles properly (should be around 3 turns) and then adjust your HPR for velocity.
