You're *kinda* right... The trims don't grab based on how quickly the train has done through the course, but how fast it's going at the moment right before the trim. There are speed sensors right before the trims that read the speed on the train and adjust the trim brake as necessary to control the speed of the train. That's the reason that on colder days (and in the mornings) the trims aren't even used and then as the wheels warm up and the train speeds up the trims tend to hit. And on really hot days, the trims will hit hard if the train is going real fast.
As far as B&M's hypers overshooting the brakes, I don't see how that's possible on the newer hypers because they have magnetic trims before the pinch brakes and those magnetic trims slow the train enough that the pinch brakes can easily stop the train without exerting much force.

They are there for more consistent intervals, and I don't really know if there's any more reasoning behind it. I think maybe they are there to keep the train from overshooting the brakes (I've heard that SFOG had a problem with Goliath doing that when it first opened), but I really don't know.
