After reading this Meta.SE post and reviewing this question and answer I can't seem to work out why the progress noted for my 'curious' badge is only 2/5 instead of 3/5.
I don't have a positive question record:
(total questions - negative questions - closed - deleted)/total questions >= 0.5 (4 - 1 - 1 - 1 )/4 = 0.25
(darn that stupid question that got downvoted, closed and then deleted! Perhaps a speedy 'delete before it gets closed' would have saved me a point!)
So I can't earn this badge until I ask at least one more positively received question that is neither closed nor deleted, but I have three well received, open, undeleted questions - wouldn't that mean that the badge would read as 3/5, positive question record required?
Added both bug and support tags, as while I'm guessing there's some functionality here that means the tracking is, in fact, correct, this could be an incorrect guess. Also, if I'm right, maybe there's a good place to clarify how this feature works more fully.
