I am reading very fast, with about the same retention and lack thereof as regular readers. It's a simple speed advantage with me being neither better nor worse in retention.

I consider this a simple skill that's useful sometimes. e.g. in exams I got a few minutes more than most other people, simply because I read the questions quicker.

But in the end we have all our different talents and aptitudes, it's not a contest. I have a harder time copying what people show me physically than other people do for example. Other might be amazing at that and very quickly pick up something that is shown to them
