Help me understand GAC skill level, league

I just looked at a bunch of those accounts in Carbonite 3, and it looks like none of them have swgoh.gg pages, which usually means they're very new to GAC. They all also have GPs that are right around the cutoff for the initial GAC seeding. Basically - these are accounts that have just hit level 85 and are participating in their first or second GAC event. Their initial skill score is based solely on their GP - so some of them would have joined last week, and been matched against other brand-new-to-GAC accounts (thus being able to go 3-0, despite the weaker rosters). Others may have gone 2-1 last week, or be brand new this week. I imagine you'll eventually be able to climb over them, but that is interesting. It does seem like the top of the division will be continually replenished with new accounts, and some of them will inevitably go 3-0 since they're mostly matched against other new accounts.
