Hi there, number of first replies refers to the total number of first comments on overall topics during the timeframe which you've selected.
So, if you had 10 topics, and only 4 have received a reply (so 6 topics have none) then 4 would be the total first replies.
However, if you had 10 topics, and only 1 topic has received a response, even if that one topic has 5 total replies, your total first replies is still 1.
Hope that helps? It's a bit confusing - also make sure you're paying attention your timeframe - if a first reply is posted to a topic that is super old, it will be included and your average minutes to first reply will be skewed.
