I have specifically waited for the ball to settle and have still gotten the "plunge to nowhere" result.Hadn't noticed it being inconsistent, and the skill shot aspect isn't that hard to do, except I forget about it half the time and plunge too hard. : P
The thing with plunging and having the ball go nowhere can be done on any table, just pull back the plunger before the ball is settled in the launcher. Irritating and an obvious, basic problem but they've never touched it.
