2v2 ladder currently: every team has moved down in rank, except for 3 who have not moved. But there's only one new team. Fuh?

The team in 3rd have moved down a place, but 1st and 2nd are still the same? Snuh?

Maybe it's about points and not rank ??

Arrows show the change in rank from one week ago

Srsly, in the top 8, it says that 5 teams have moved down 6 places in total. The other three teams haven't changed. Druh?

I am pretty sure it is thanks to Ineffable and Mirror rejoining the ladder. The arrows show the change in rank from one week ago (or when they quit the ladder and rejoined, it goes back to 7 days ago that they were in the ladder for them.) I don't know if you understand what I'm saying but they left the ladder for a bit and then came back within the last week. The arrows don't necessarily show the change in rank from one week ago, instead they show the rank from 7 days ago in the ladder. Meaning if you drop out, you can come back in 2 months and still have an up or down or equal sign instead of a new sign.

Hmm, okay. That's confusing.
