Yes, exactly. There is the one and other discussion about reactions going on here, see here for example:
Unfortunately reactions still do not count as likes for trust levels. For our community this would be a real enhancement, as reactions are a lot more used than likes.
I also would say that negative reactions should count different for trust levels. But should there be a difference for a statistic which simply counts the number of reactions (or likes and reactions together).
Anyway, maybe you want to join the other topic, too. I also might ask if something is planned. 
About the statistics on the About page I cannot write more at the moment, except that I am thrilled to see more there.
