What are those large numbers on reading stats?
The numbers 38, 41, 45 in the picture above represent the overall story rank in most views. In the example here, the stats are showing Fantasy stories, by most views. So Rich Boy is the Number 1 Fantasy story by views, but number 38 over all. Broadswords is #3 in Fantasy, but #45 over all.
IMPORTANT NOTE: Over all rank is a cached value. This means is not updated in real time, so it is entirely possible to be looking at the unfiltered list and have the large number not match the order. It will within a few hours when the value is re-cached.
