Ive actually just realised one of the reasons as to why the brake run is 'so long' and in the position that it is. I never noticed but if you look carefully, you can see the trains actually leave the station and make a u-turn before heading up the lift hill,, instead of going straight out and up (like diamondback, intimidator etc)
So then when you look at the brake run, it seems fairly normal, cos as soon as it flattens out it goes straight into the station. I didnt notice this until re-watching the off ride animation a few times. I dont think its a u-turn like Nitro's, but just Behemoth continuing on another 90 degrees.
(you can see leviathan will have that turn right at the beginning and end of the off ride animation)
