It looks like BTW wasn't reset and their points were just hidden due to inactivity anyway, but 8300 points with 13 wins (if that's true) does seem weird considering you'd need to go 13-0 and probably only spar against tags with 7500+ points
I hope the New Guild System™ will bring something better to GST seeding because it's rarely an organic process, and I'm sure the majority just find it to be an annoyance in its current form
