They're all marketing slop lol. Go look at their methodology. Absolutely shite.

This is what you claimed the bar was "it just should be higher than 'I feel like'"

Now you are moving it because your statement is provably false.

Your criticism of it is based on vibes. What specifically is wrong with the methodologies?

One of them broke randomly developers into two groups, one with access to ai and one without, timed them to complete the same task, and compared the results. That seems fine? Any measurement of performance in a lab environment comes with caveats, but since real world accounts you dismiss as vibes, that seems like the best you can do.
