+19% slowdown on average was observed in the first METR RCT study published in July 2025: "Measuring the Impact of Early-2025 AI on Experienced Open-Source Developer Productivity"

The spirit of this market is to compare both studies apples-to-apples. Hopefully METR will officially tell us what the second study's equivalent percentage figure is, that can be directly compared with the first study's +19%. If not, this market will resolve N/A.

The bounds are left inclusive and right exclusive except for "+15% to +20%", in which right is also inclusive.

If no second study is published before 1st August 2026 this market will resolve N/A.
