I think one of the factors you are missing is that we haven't had dyslexia all our lives. We have read the unscrambled version so much that the scrambled versions rarely deter us from reading at normal speed. But a real dyslexic never had that chance so their struggle is far greater. It's like when you come across words you don't know or can't guess. Even when you stare at the word for quite some time, you can't make sense of what it is.
