SEN 1st seed from Group D

A quick question, how can we say that G2 is the first seed for sure? Sen still has to play F4Q right? and if they win they too will have a 75% win rate (3 win and 1 loss).

Hypothetically if the match against F4Q went like 13-0, 15-17 and 13-0 in favour of sen (Sen winning 2-1).
then SEN would be in total 115 / 83 in rounds and their round differential will be +32. This is more than that of G2 (whose round differential is +31 114 / 83) and hence they would go to become the first seed right?
I know this definitely won't happen, but Riot should still have to wait before making the draw right?

Am I being stupid or theoretically is it possible for SEN to get first seed?

I think if it comes down to a tie it comes down to map record, and G2 has won 3 and lost 2 to SEN

No its not possible, they just looked at the head to head matchup.

NONO

it's h2h RD

So they check h2h map record over overall round differentials? that seems odd. (assuming the above scenario where SEN has a higher round diff)

Ohh okay makes sense ty
