Here's some info I'd like to share to others who dont mind doing adjustments/tweaks to their games.
I wanted to see what I could do to make the garage shot from the upper right flipper easier. The shot was makeable before but since I'm just an average skillz player I wanted to make it even more makable.
Based on what was learned from adding more curvature to the rail position with the inner loop spinner shot, I wanted to see if something similar could be done with the garage shot.
You need to remove the plastics above the portal return trough to get access to that area. If you look at the intial position of the rail you can remove the second and third screw on the rail to adjust its position (very similar to the inner loop shot). However, the tab on the third screw is very close to a wooden rail which prevents you from moving it much at all.

Loosen the black screws under the playfield which secure the wooden rail to the playfield. This allows you to raise the wood rail a little bit.

Then you can slide the edge of the metal rail tab under the wood rail to increase the curvature. Tightening the wood rail screws will then clamp and secure the rail tab under the wood rail.
You can see the curvature of that rail is now improved.

If you use the original screw hole for the first tab on the rail, it will restrict how much of a curve you can create. I made a new screw hole for the first tab which allowed me to increase the amount of curvature.
The shot is still hard but now my sloppy half assed shots sometimes make it to the garage.
