I contacted Alex to ask about this, here’s his response “thanks for catching that. My fault. It can take years to publish a paper in econ so my slides came from an earlier version. We were asked to add some more experiments in a revision and so the numbers changed. The published version is definitive.”
So the pretty chart in the post should have the baseline at 44%, PE20 at 67% (higher than the current highest) and another column for P20 at 61%.

I made a new chart for my post on this suggestion.
