Thanks for the blog link, Darren, I missed your post while I was making mine. Your thread here has a lot of value to amateur breeders, though, so I hope you don't mind if we carry on.
I guess I shouldn't be surprised to find that Jaune Flamme has the Beta gene, since the data showed it so high in beta carotene. If JF had the tt gene, it would be prolycopene/ cis-lycopene instead, because the tt effect is dominant to the others.
