The entry is still throwing some people off. To give you a breakdown of how they're going through the track.
Full throttle through the first turn, let off to switch back, use the momentum to throw you wide, use the ebrake to push you out if necessary, use the front brakes to slow you down if you're going too fast, once you've gotten close to both outside clipping points slowly get back on the power to finish the sweeper, throttle some more to get past the left clipping point and left off to switch back the other way, then get back on the power again to get close to the right clipping point and on your way out be careful with the wall to your left.
