I've checked the threads going back two years and didn't find this, so apologies if it's already been asked.
The introductory text for the QQAC badge refers to "the desirable 55% to 95% correct answer range". The criteria then say "...where 55% to 90% of players answered correctly".
So, is the upper limit 90%, as the badge criteria says, or 95%, as the "desirable range" implies it could be?
lorance, who has a whole bunch of questions scoring 91%-95% correct
