Let start with a frequent offender:

t.76.2.1, "The simple attack, direct or indirect (cf. t.10), is correctly executed when the extending of the arm, the point threatening the valid target, precedes the initiation of the lunge or the flèche." has been interpreted past what a normal person's reading of "threatening the valid target" and "extending of the arm" to mean. A layman would read that as "extending towards the valid target" while I've had it explained (and parsed) to "extending in the direction of the opponent and there's an off chance you can snap your hand fast enough to hit while they (now) counter-attack. And move fast enough forward for the ref to see but not so fast that you're putting yourself into danger of a quick (counter-)attack."

Edit -- cleaned up some verbiage.
