Azircon, there is actually an information you're missing here. The main trail votes were led by Calumam, Calumam took a short break and that was why he didn't vote a lot of posts. Before the break, Calumam (and thus, the trail) was voting way too many posts and authors than this. Please I would like you to make a correction now that you have this info, it can only be the right thing to do.
To support what I've just said here with charts and graphs is a little much for me to do right now, I apologise, but I'd point to the #pob-wotw tag, check all the posts that have been made under that tag over the months you'd find the trails' votes on them a great lot of times. (I point to this tag because that's where Proofofbrain Community's most quality posts usually fall on)
