Figure 21 shows that initial implementation time (which I take to be time to PR) increased as well, although post-review time increased even more (but doesn't seem to have a significant impact on the total).

But Figure 18 shows that time spent actively coding decreased (which might be where the feeling of a speed-up was coming from) and the gains were eaten up by time spent prompting, waiting for and then reviewing the AI output and generally being idle.

So maybe it's not a good idea to use LLMs for tasks that you could've done yourself in under 5 minutes.
