I also have had a bias about her, mainly due to magazine articles. A good friend of mine is a good friend of hers. I still question her claims, but if you consider motown at the time. No one knew who they were calling in and it was common to have multiple bassist to record the same track and go with the best or even the best parts recorded. Also think about the whole boys club thing and the fact that none of the players really got the credit they deserved. If I feed my family by doing studio work and my future gigs were based of of my prior resume, I would take credit for everything I was associated with, even if they only used one note that I played.
Her teaching methods are solid, her place in music history is amazing
her theories in intonation and setup.... well
Remember your seeking her as a teacher not a soulmate.
