Cons of the system with 16 groups of 4 people:

1. In some groups, everything will be decided on time (and in some even ahead of schedule, given a clear certainty regarding place distribution). Others will require additional games, sometimes 2-3 rounds (for example, this happened in "allrandom", where a situation occurred where "seven are waiting for one"). It should also be noted that there will be no fast games, such as the SoD template on 10 minutes.

2. What is the point of spending 2 months on a preliminary stage of little interest if it's followed by a "lottery" Olympic stage; wouldn't it be more logical to play for elimination right away?

3. Experience shows that on "long" templates, the fewer insignificant games there are, the better for the participants.

P.S.

Experience regarding additional indicators in relation to groups of 4 people is completely unsuccessful.

Berger and head-to-head encounters do not work in most cases.

For example, in my group on "allrandom", a situation arose where between Artem - Cobra and myself, the one who played sooner against Marajan—who by that time had already lost his chances—would advance to the next stage. We decided to play additional games to avoid this absurdity.
