Ok, went down into the game dungeon and I've got mine adjusted where I want it. Few notes before I start:
Where I want it - ball exiting ramp hits the flipper about 1/3 of the way down from the pivot point. It bounces back up into play if the flipper is down. If the flipper is up it will go up the in-lane. Seems very consistent.
1 - To test your adjustment, simply feed balls into the catapult directly buy lifting up the cover plastic in the lower right at the fishing lure which sits just below the reel. You only need to lift it up about 3/8" and the ball will slip under and drop into the catapult. When the game sees it in there it will launch it.
2 - Feed balls into the catapult in attract mode if you just want to see how they land on the flipper.
3 - Hold the flipper up with your fingers to see how it reacts that way.
4 - If you start a game you can obviously use the button to hold up the flipper but the ball search and whatnot can be distracting. Test mode will not fire the catapult with a ball in. Coil test doesn't work either as it's a short pulse and simply puts the ball into the bottom of the plastic. OUCH!
5 - I only needed to pull off the plastic over the adjustment screw and remove the adjustment screw to lift the ramp and bend it with my hands and pliers.
My ramp was bent 6 ways from Sunday so I basically had to bend everything in some fashion. I "restored" it to the way I believe it appears in the manual and on various WMS published things (like the flyer). The result didn't take me too long to get to and it seems to work very well. I had no issues with SDTM. Only long term testing in game play will be the true test but I played multiball with the glass off several times and just hand fed the balls into the reel. Here's the corrections I made.
1 - The longer lower right ramp rail was bent to come straight off the ramp when looked at head on.
2 - It was also bent so that it would be parallel to the playfield when installed. (easy way - eyeball to the top of the right loop ball guide)
3 - support bracket off of the lower right rail is bent at 90 deg angles to form the "Z"ish form.
4 - support bracket foot should end up sitting "flat" on the PF without screw tension.
5 - alignment of the ramp when looking overhead is such that it essentially follows the contour of the right/long cast loop ball guide.
Here's some pics of the completed product.
