I don't think one could argue that, seeing how often this is a problem.The thing is that even with a better base technique he'd still be good sometimes and bad at other times, base technique isn't the only factor determining performance, and one could argue that it's in fact a minor factor.
I have to wonder if they ever actually taught him the theory behind it. Because even when you are in doubt or in fear, that can help you get through a tough corner, you just need to remember it. They once wanted to send him on a workshop with Cal Crutchlow. It was one of the best ideas they ever had. But they didn't go through with it.
