I used to own one but don't remember. Looking at pics of the playfields on the internet including stripped ones, to me it appears they were set up using the liberal position (divots closer to the sides) but I can't verify that for sure.

Correction, I meant to say the divot positions towards the outside on the side drain posts is the conservative setting. Are the solid lines considered the 'factory' positions? The 'see note' adjustment, looks like it's moving the target itself forward/backward (?)
