Spot on Ben!
Turns 2 and 12 are great for identifying visual skill weaknesses. To many riders, they look pinched or appear to close up (ie, the exit is more narrow than entry). But as you have ridden, those turn's exits are just as wide as the entries. The challenge is to SEE IT!
When you see it, rider's can adjust their turn in point and rate to adjust for a WOT line through the corner. Lazy turning and WOT through turns normally don't work out too well.
Until then, SR's will always have the rider rolling off or setting an entry speed that leaves the rider let's just say... wanting a little more.
