There’s a lot of problems with this. Just some include that it’s a blog and doesn’t link to the actual study so it’s impossible to see what’s going on with the this report. They also never explain what this “reliability score” even means or what’s included in that. Then they start doing things like using a percent to compare the scores saying this is percent more reliable. But we still don’t even know what this score is, and comparing as a percent may not make any sense to say depending on what the scores are and how they’re calculated. Unfortunately you can’t really draw any conclusions from what’s in this article.
