Somewhat similar figures here on the distribution of time to complete tasks; slowdown from AI use most apparent on tasks that take longer.
At the beginning of the study, developers forecasted that they would get sped up by 24%. After actually doing the work, they estimated that they had been sped up by 20%. But it turned out that they were actually slowed down by 19%.

This reminds me of this paper, which gave randomized access to GPT-4/4o for checking the reproducibility of economics papers. Teams with LLM access took longer to assess computational reproducibility (but not statistically significant).
We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.
