It's an extreme minority opinion among programmers that typing speed matters, but I started writing again recently and I feel like the argument in https://danluu.com/productivity-velocity/ is still obviously true.
wc has the source for my last post at 20k words. At a hypothetical 100wpm, that's 3h20m of typing time. I often do two passes and totally re-write it, so it's really 7h40m.
If I were to type at 50wpm, that would add a huge amount of writing time, both in absolute and %-age terms.
One could argue that I should optimize my process and only do a single pass, but this two-pass process is done instead of the various standard techniques people suggest, like outlining or w/e.
When I've compared notes to people who do standard stuff, my process is much faster, so I don't know of standard advice that would help.
I think just doing a single pass without using some kind of organizational technique wouldn't work unless my working memory was like 100x larger, so that's also out.
I do often write the shorter stuff that goes on Patreon that's "only" a few thousand words in a single pass, but the set of things I need to hold in my head to write the way do I do is highly super-linear and I don't think any amount of trying harder, practice, etc., could make this work for me with a 10k word post, let alone a 20k word post.
It really starts falling apart around 5k words or so and I haven't (yet?) found anything that's more efficient than just doing an entire second pass.
