Definitely some interesting results, though I wish they went into a little more detail on their methodology. For example, is lower case better because it’s harder to read Titles With Every Word Capitalized? Or is it because PR titles in ALL CAPS tend to get ignored for being annoying which biases the results against capital letters?
Also I don’t buy their time saving numbers at the end. According to their own numbers the average dev spends 1.34 * 590 = 791 days per year waiting on review?? At least at my company I’ve never had to sit and wait around for a review, even if thr PR is blocking some other work there’s always been unrelated stories to do instead.
