Brian my friend, I’m not asking because I think I need to be writing a certain speed. I’m asking because I’m curious. 🙂 You are correct that it doesn’t matter what a writer’s current speed is, and again, I didn’t ask to compare myself to others to see how much better I needed to get. However, as in all academic and career arenas that someone is trying to become skilled in, one should always try to improve themselves and become better, that includes your writing fluency, speed, and value of prose.
But again, you’re right, no one should ever get bogged down in comparing themselves to others. 🙂
