Nothing wrong with that speed. It's a few characters above average, I think.
Of course, there is a difference between typing something pre-written like is done on a typing test, or something memorized, compared to typing something as you think of it, such as when you are doing an email.
I go from the mid to upper 60s on average to the low to mid 40s when typing real world stuff on the fly. I don't know if that kind of ratio would always exist. To make the math easier, let's say my normal speed is 60 and my real world typing drops to 45 - a 25% drop.
Well, what if my regular speed was 40. Would real world typing drop to 30 (25% lower)? Or would it drop by the same number of 15, meaning I only get 25 wpm. I can see an argument that the reduction may be less because I'm already typing slower, giving me more time to think of what I want to write, but I really don't know how it would work out. Would make an interesting research project!
But I decided some time ago that accuracy is more critical to me. The typical standard for most jobs according to what I've read is 97% accuracy. Sounds good until you realize that it actually means one error for every 33 characters! Raising it to 98% doesn't sound like much, but that is one error for every 50 characters. And my target is 99% so 1 error for every 100 characters. At least on typing tests. I may not be that accurate when typing emails and posts because I'm sure the process of thinking about what you want to say may take away focus on accurate typing.
In any case, your speed is fine and you seem to be adjusting to touch typing just fine.
