Nothing has changed. I am certain that scores don’t play any role in this. But, the number of competitors has an impact on the ODDS of an identical re-bracket.
From high-school math on “factorials”...
If there are two competitors then there are only two ways the brackets can be created.
2 x 1 = 2
So, if you bracket / de-bracket / bracket there is a 50-50 chance the brackets will remain the same.
If you go up to 3 competitors then there is a 1 in 6 chance...
3 x 2 x 1 = 6
If you go to 10 competitors it becomes...
10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 1 in a shitload chance
Yep i understand, maybe it was just a fluke instance when it happened. Cause less than 1% isn't favorable odds for a repeat.
