well at present day, 100T would beat all 6 teams under them so regardless of your rule this is at least an exception to it
wym? did they announce the details of the formatting of the group stages or are you just assuming its not going to be a round robin format? If they did announce it i hadn't seen it but if it isn't round robin that sucks. Regardless two games (and even less games for some of these teams) isn't really a good sample size to determine team quality esp when teams have just picked up players (i mean 100t is the prime example of this they've hardly had any time with their IGL)
I'm sure there is on paper but with productions in real life its so incredibly difficult to account for delays so practically probably not. i mean just look at this last week or so with all the tech pauses we've had not to mention even a series going long due to a couple overtimes or one really long one. This stuff isn't unheard of and is common enough to be a pretty big factor. You need redundancy built into schedules like this and a 4 day schedule would destroy that.
like one of the groups could be LOUD LEV NRG SEN 100T and then one of those teams would be fucked again
well seeding is a thing (actually one of the few uses for consensus since thats pretty much the only metric available in the pre season) so that isn't as likely but any team that seems weak initially then turns up (heyo EG last year) could cause something like that. remembering back to 2022 there was always a somewhat stronger group but never enough that a team didn't make playoffs that actually had a shot a qualifying for the international event.
