I guess my point is that Parks book has very clearly displayed, on the pages that we are discussing, a picture of Kurtis Roberts not using the technique we are talking about. Now he is countersteering, in fact the bike he is on is
well layed over at Daytona, so he is countersteering his ass off. However his outside arm is clearly not relaxed.
So either Kurtis is unfamiliar with the "push right - go right, push left - go left" philosophy or he subconsciously tensing the outside arm without realizing it. I am buying the latter, and Parks backs this up. He talks about riders doing this as the lean angles get steep. For those not familiar with the younger Roberts (like me), here is a link:
wikipedia. If someone of his caliber can make this mistake, I think we can discuss it here.
