Wow! That is a lot of experience.

I guess that my experience have been a little different (35y of programmer, but max 8 years with the same software).

Anyway, I am intrigued. 40% of writing a day is a lot, more that it seems. I did a calculation around 10 years ago, and, if we think that:

- the average typist speed is around 35 words per minute

- 400 lines of code may contain 1,000 words

That is 400 lines of code in 30 minutes.

If one work-day is 8 hours, the 40% it is a bit more than 3 hours. So, around almost 1,300 new typed lines of code, every day. (We are talking about averages, not counting copy/paste or GH Copilot).

Do the numbers match your experience? Do diffs support this?

(That is how I analyzed that initially, plus recordings of the activity during the workday)

Thanks! I am Really intrigued!
