Would you please give me a link to that video? (Salsberg & Slavik) I would be very interested to watch it.
With regard to the 75%, they are right. I find that at competition, under pressure, I fall back on my muscle-memory, even if that move was proven wrong and corrected long time ago, unless I concentrate to execute that particular movement correctly.
