I agree with the analogy, but not the specific example. You're training muscle memory: 100x repetitions are nowhere near enough to make a kick seriously effective.
10 kicks 1000 times, though, is enough to start being alarming. It still wouldn't worry Bruce Lee, but lesser mortals might start getting cautious at that point.
It's an analogy. From experience, one practice session alone can involve practising one kick 1000 times. Pretty much every trained karateka has done each kick more than 10,000 times if we're being literal about it.
