We'd have to lay some ground rules...what counts as a shot? Only things you can make cleanly (ramps, scoops, orbits, loops, saucers) or all potential scoring targets (standups, drops, bash toys, magnets, optos)? If a target can be hit by three different flippers, does it count as three different shots?
Depending on your definition, you'll end up with very different results when you go a-counting.
