Second this. I've done something similar in the past, but I won't count narrow standups at all, and target banks (standups or drops) count as 1 shot. One game having a ramp with the blue nubs at the entrance is the same to me as a ramp with 2 narrow standups at the entrance sides. For me, I was looking at something like unique or quality shots in a game.

So to me...
ST Pro = 12 unique shots (shield bank, scoop, through spinner, lock bank, warp ramp, alpha ramp, under ship, black hole, beta ramp, right orbit, behind flipper, torpedo bank)
Stern Kiss = 9 unique shots (Kiss bank, through pops, scoop, Starchild, center ramp, Gene head, right ramp, right orbit, Army bank)

From there I look at how good they're used. I think ST is a much more fun game than Kiss because not only do I see more shots, but I think they're all used very well. What makes my head count interesting is when I come across a game like EBD, because it would have only have a couple of shots but they're used very well.
