The statistics says, “Studied 111 cards in 8.92 minutes today (4.82s/card)”. This seems to be the average answer time. I think the median time would be a much more interesting statistic.
The average time includes outliers, cards with long answer times, which could be yourself looking at study materials to check the card information, or sipping your tea, or petting your cat. These outliers can significantly skew the resulting number. A median, or perhaps some other method of calculation that would get rid of the outliers, might provide a better representation of how quickly you can answer a good card, or of the quality of the cards themselves.
Might be interesting to put this number on a graph, too
