In this case better would mean, understanding exactly how torrent works, seeding to a 1:1 ratio, not .2:1 OR 1000:1, not being an acc's collecter and never leeching anything off the site etc..
It also would mean not buffering 5tb's of an acc to have a 1000 ratio to use as a screen shot to get trackers in giveaway's.
to quantify the "average" user, you would get
1. The average connection speed of all fst's members
2. The average age of all the users
3. Average time of the average time user's leave the torrents seeding
4. You would run an A-nova statistical test to check for general knowledge etc... Okay u get the point
