Playfield cleaned. New elastics desperately need changing (lol).
Reproduced the problem, which was basically the launch plunger was pre-extended and giving weak launches. It seemed associated with weak right flippers. Raised the playfield, inspected right flipper button switches, lowered it for another look, and the problem was gone.
This one may arise again.
This Pinside thread talks about this particular issue

Its possible that the right flipper button is aftermarket and pushes further than the stock one would?
Easiest way to reproduce problem is to hold down right flipper button while firing the ball with shifter.
Game was missing a ball, adding another ball fixed the switch and trough issues reported by game
Status changed: Broken → Good
Replaced flipper linkage and related parts from a rebuild kit.
Found right flipper linkage completely broken. Left flipper (blue paper) shown for comparison
