Ah, what you're describing is a "superboost". Sometimes it's easier to abuse these triggers by spamming crouch, or jumping on them. I've done some logging in the past, the game basically sees the player touching the push trigger, leave it, then touch it again, essentially activating it on the client twice, instead of just once. Sometimes it can happen more than twice, depending on the situation and trigger, some are easier to abuse.

Can't say I've really done anything with this information, just wanted to explain it, and possibly someone might have a solution for this.
