Earlier in this thread you reported an absolute limit of 60 WPM for yourself, but an average sustained for hours of 16.7 WPM.
I'm sorry for not explaining myself properly. The 1000 words per hour figure includes all the necessary thinking time - ie composing what I am going to write. I shouldn't have introduced that, in retrospect, because it isn't much to do with raw typing speeds. I introduced it because a fellow student bet me I couldn't write a 1000-word essay in our 1 hour break, because it would take him so much longer. Technically he was correct because after 980-odd words I was at a good place to stop, but he declared it a win anyway. 😁 But you are right - it was misleading and irrelevant.
My main point above all else is this:
A number of us have shown results from a typing site of somewhere in the 40s WPM, in a 1 minute test, self-taught.
Maybe you're genuinely a bit faster, but it seems to me being in the 40s is Good Enough,
Again I obviously didn’t explain myself properly - my apologies.
It's not about speed - it's about how much less tiring it is to touch-type than any other form of typing (in my personal experience and observation of others). A non-touch-typist could certainly match me in speed, but the massive benefit for me is that I can keep typing for hours with very little fatigue. Far, far less than when I was typing with my personally-developed super-slick version of hunt-and-peck.
In the experience of me and others, the cognitive load from touch-typing is significantly less; enough to make a useful difference.
I did emphasise that in my first post: it's about keeping up the pace for a sustained time. That is where the gains are. And interestingly, even when I'm operating at my composing-plus-typing speed of an easy 1000 words per hour, it is still less tiring than hunt-and-peck.
[...] not worth effort improving, especially given a much lower average speed needed.
Well, of course, everyone knows their needs best. For me it was a great decision to learn touch-typing. I described the circumstances where it proved valuable: essays, assignments and dissertations at university; technical authorship; and writing reports and training material while I was at work. Obviously if your workload is different then your needs will be different. I don't believe I suggested
everyone should learn to touch-type; if it came across that way then I apologise.
The original question was "Do you touch type", and my response was to say 'yes' and explain why, plus give some observations about the learning process itself.
