WPM is an archaic metric, and as my top speed I target only a reasonable conversational pace in chat windows, comparable to verbal conversation. Anything more is kind of a waste. As long as people don't feel like my pace of typing is lagging during a chat, I don't really need to be much faster than that.

I don't have a problem meeting those demands, and composing my thoughts, and contemplating what I wish to type usually consumes more time than the act of typing itself.

Bandwidth measured in bytes probably makes more sense these days. But again, I haven't bothered to measure how fast I type, other than a gut intuition for how often I get sniped in chat rooms, when people beat me and say something before I can, alongside how impatient people seem to get with me.
