Smokey, surely the speed/rpm limiter can't brake for you.  It can't bring you down to the set engine rpm but can only stop you from going through it on the way up.  They must have to judge the speed somehow to ensure they are at or below limiter setting then accelerate up to the limiter before they cross the loop. If they haven't lost sufficient speed by the time they hit the pick up loop, they will incur a penalty.
