You're overlooking the throttle and bike control you need for corner 3. Also, Fabi has the perfect mix of every other kind of corner - carousel, late apex, tight hairpin, sweeping right and left-hand corners, et al.
You can see it as frustrating... but you could also be stuffing your competitors in that corner just like they try to do to you. That's racing...! You should see one of the car competitors I drove against a few years ago... that guy would literally throw his Corvette through corner three and the hairpin so violently that it looked to the observer that it wasn't possible to keep it on the track. But he did... and to devestating effect, in the points. Fabi is where he took me in points to drop me to 2nd place in 2000.
