I will TRY to explain. Imagine going down a straight with an upcoming some what tight left hander, your in fourth or fifth gear with the motor tapped, what do you do, you grab a handful of brakes and MAYBE down shift a gear if it does not cause too much rear wheel hop. This is where the comp release comes into play, you use the downshift (or 2) to come in hot & let the motors gearbox be the Controlled engine braking (which feels much like a current F four stroke) and with a turn left, then right, the rearend steps out smoothly & controlled. If anyone has tried to go fast on an oval before will tell you, you have to be aggresive & smooth to have good lap times. Next time you go riding, try downshifting 2 gears with the clutch out & see how much engine braking is actually in a 2 stroke, it's just not smooth like a 4 stroke. I hope this gives some what of an explanation.
