Interesting that it was put on her list, but more interesting was who else recommendeds it... Leadbetter.. I was told a while back that he has his instructors read it as a requirement but can't remember who it was, it might have been one of his instructors this seems to confirm this. Now the question is how or do they apply it directly or indirectly..??
I don't think she should read it on her own unless she really understands HER stroke, having AI work with her, would be a better way to approach it IMO.
Interestingly enough, I spoke to one of Lead's instructors when they first opened shop in Singapore about TGM reading requirement.
He says that they were "encouraged" to read it as opposed to "have" to read it.
