John,
I doubt there is much of anything to give us a real insight into how Raynor would view other's work. Like many, even today's, archies he was pretty focused on his own projects and methods.
That said, I think it is a real shame that engineering types, especially Raynor, aren't given to share their views on functional and formative matters. I'm pretty sure that had Raynor been a critic his insights on the functionality of feature design, placement, and relationships would have been facinating. As a sidebar I'd day they are much needed today as a reference for modern design which, in my opinion, at times is a bit heavy on the aesthetic and a little lite on substance. I doubt his style / fashion comments would have been studied by many, but the flow / structure could have been a text book.
A better question might be. Had Raynor actually written down his thoughts, would anyone be able to understand them???
Cheers!
