I was able to get the same colors by refreshing a few times earlier, but a screenshot will work just as well as you suggested. Ham Sandwich, what is the difference between needing to get 95% right and needing a 95% confidence level? If you don't get 95% correct, then you don't have a 95 confidence level. Semantics my friend...
No, there is a difference. For example, if someone scores 10/20, he got 50% right but there's not a 50% chance he was guessing. There's nearly a 100% chance he was guessing. And if someone gets 20/20, he got 100% right but there's still a > 0% chance he guessed.
Are we allowed to do this with an increased color difference? Because with a 10 color difference, I scored 20/20 easily. Which, I think, proves that the ability of an ABX to show differences relies on the magnitude of the differences, and by extension means that if people can't pass DBT cables tests then the differences may well be too small to easily perceive (if they exist at all).
