Did each developer do a large enough mix of AI/non-AI tasks, in varying orders, that you have any hints in your data whether the "AI penalty" grew or shrunk over time?

You can see this analysis in the factor analysis of "Below-average use of AI tools" (C.2.7) in the paper [1], which we mark as an unclear effect.

TLDR: over the first 8 issues, developers do not appear to get majorly less slowed down.

    Thanks, that's great!

    But: if all developers did 136 AI-assisted issues, why only analyze excluding the 1st 8, rather than, say, the first 68 (half)?
