Error in advancing

Hello everybody, in a tournement group of 6, where 3 people were supposed to advance,only two are advancing. I wrote to the TD, and had no answer. Wrote to chess.com support, once, we can see with the answer bellow that they haven't understood the problem. The second answer was the silence. For me, this fact of only 2 people advancing may be a bug but anyway it's like breaking rules.Thanks in avance for all your comments and clarifications.

This is standard behavior. if there are only 3 people in a group, then only the top 1 will advance. This is to prevent tournaments from going on unnecessarily long.

The maximum group size changed from 6 to 5 when only 15 players got to round two.

The rule is 50% or less of the maximum group size advance, unless there are ties.

If 16 players had advanced to round two then the maximum group size would have remained 6 (5 + 5 + 6 = 16). Three players would have advanced from each group.

In this example more than 50% of three groups advance because the fourth group is bigger than the rest. Nominally 2 of 4 advance but in this case 2 of 3 advance:

In this example, without the 50% rule two of two players would advance from group 1.

Just in case I was not clear, there is no error in advancing.

Hi Dude, thank you for your comments, they were clear, but I still don't agree with what happened. For me, the rules are being broken, since the tournament in question is 6(1)->3, and therefore 3 people per group should advance for the third round, and not 2, even if the number of people per group in the second round droped from 6 to 5.

Chess.com says: Can you explain the tournament format. What does 5(2)->2+ mean?

()->[+ = No Tie Breaks]

Example 1: 5(2)->2+ means 5 players per group, playing both games per opponent at the same time, 2 players advance from each group, and no tie breaks.

Example 2: 8(1)->1 means 8 players per group, playing one game per opponent at a time, 1 player advances from each group, and use tie breaks.

So chess.com doesn't say anything about what you said, that "The rule is 50% or less of the maximum group size advance, unless there are ties".

Did you deduce this, or is this writen down somewhere I could not find?

If this rule has been writen down somewhere and not deduced by you, in my opinion this is a flaw since 50% or less can go down to any number. In the case of the tournament in question, where there were 15 people in the second round (divided in 3 grouops of 5) trying to advance to the third round, this 50% or less could have been 7, 6, 5, 4, 3, 2 and 1. So why not and who decides that only 3 people instead of 6 would advance to the third round (which would mean 1 and not 2 per group advancing, instead of 3)?

If the rule has not been writen down and you deduced this from your experience, it thus means that the rules have not been pre-stablished, which is not acceptable for a tournament. Imagine a tournament with learn by doing rules...

Cheers
