I've seen it mentioned that the target times for individual Q's are "calculated from top scorers," but what is the cut-off here? I realize that I heavily weight my speed performance off of these target times but they vary wildly especially when compared to that state showing how likely percintiles for given Q get them right, for example "75% [175]."
Is the target time based of of the average time like 175+ scorers get the question right in? Sometimes I get a question done much faster on hard ones, but then the percintiles data will be "75%[164]" which seems to imply that this "hard" Q is actually an easier "hard" Q. So if that's the case, is the target time on this Q using the average of the 164 scoreres for its time calculations? If not, and its still using the generic "high-scorers" (which I presume to be around 175+?), then why is would the target time be so high on a given question with such a low 75% percintule score?
