24% PRs isn't 24% more productivity. Lines of code isn't productivity, and neither is CLs landed. What's the feature velocity of the team? How much time is being spent on rollbacks, outage responses, etc.?

Here's a quick hack to triple your PRs landed: Land a PR, then land ANOTHER PR undoing that one when you realize it was full of bugs, then land the PR again once you realize management doesn't care about quality, they just care about the number of PRs landed.

The 24% more PRs was merged, not «landed». Presumably after human code review (but I didn’t check the paper…) Not sure about this particular study, but I «think» my own productivity (coding wise) has improved by more than 30%. In many ways I wouldn’t even have started on many of the things I’ve completed these last six months because I would have viewed their effort to be insurmountable within my time budget as a professor (with all my other duties).
