I was comparing Rocket III to Fast Draw, which plunger works good on, and the difference seems to me that the plunger works better when it extends 2 or 3 mm above, or through, the walls the ball rests on...Rocket plunger set to y-1057 works good for me. Also, if the walls the ball rests on are not equally spaced from the plunger, then the ball sits a little off center to the plunger and when it hits the ball it puts a lateral force to it...at least that sounds good in theory.
**Nevermind, I just saw where you fixed that in arcade version***
You are right. I just put the plunger 2-3 mm above and it's work fine (I hope). But, with the initial position, the plunger is in a good position (when you pull it, you see the ball falling). I have to mark that on a post-it in order to remain it...
Thanks for your help.
superb release my friend! excellent job
