I believe what she's saying is that the pastel gene has been bred out by a lot of people. Some people started with sub-par single gene pastels and bred them to dark normals or other sub-par quality genes. These sub-par parents will generally produce sub-par offspring. So, if the person who bred the snake in question is working with two sub-par single gene pastels, that the single gene pastel offspring would also likely be sub-par. If the breeder is producing sub-par pastels, it is likely that if they hit the super, it would also be of sub-par quality. So, it's possible that this is a super pastel created by two sub-par single gene pastels, which results in a sub-par super that others might mistake as a single gene pastel.
Clear as mud now?
Short version... It's possible that this is a low quality super produced by low quality pastels...
Understood. But the super pastel should still have a little blushing even if it is super low quality, no?
