Premier Pools

Premier pools will be seeded using a reverse snaking method. Top 2 in each pool advanced to a slotted spot on the Pro Bracket. The bracket slots may be altered slightly from traditional formatting to avoid pool play rematches.
 
Reverse snaking is when after completing a full "snake" aka seeding two teams in each pool, the next "snake" begins at the opposite end of pools.
 
Ex: 8 teams -> 2 pools
First snake
A: 1,4
B: 2,3
Second snake
A: 1,4,6,7
B: 2,3,5,8
 
Why reverse snake?
Reverse snaking has been used at the last two Nationals Pro Divisions. With reverse snake strength remains evenly spread amongst the divisions, however matchups are changed. These changes give a slight benefit to the top seeds and evens the playing field between middle of the pack seeds. With standard seeding, certain second seeds have distinct advantages over others. This advantage still exists with reverse snaking, but is diminished slightly. The second seed in each pool all have a relatively even third seed that they must best to keep their top spot.
 
Why are not all divisions seeded like this?
With only top 2 making it out of the pool, individual match-ups are slightly more emphasized than when every team makes the bracket.
 
Shouldn’t certain seeds have more of an advantage?
Yes, and they still do. However we believe the advantage was too big and this now lowers that advantage slightly.
 

Example of “advantage” given by Standard Snake.

A: 1,8,9,16

B: 2,7,10,15

C: 3,6,11,14

D: 4,5,12,13

We will look specifically at pools A and D.

In pool A, in order to hold their spot in the top 2, team #8 must (essentially) beat two of these three teams: #1 (who is the best team at the event), #9 (who is the best team below them), and #16 (worst team at the event). Yes they are given an easy win with #16, but since they most likely need to win a second match to move on, #1 and #9 are the hardest teams they could possibly face.

Let’s now look at pool D. In pool D, in order to hold their spot in the top 2, team #5 must (essentially) beat two of these three teams: #4 (who is the worst team above them), #12 (who is the worst team of the next four below them), and #12 (the best of the bottom 4). In this case, two of these three teams they have to face are the closest to their skill level as possible.

Team #5 holding their seed is immensely easier than #8 holding their seed, however it is still challenging to them both.

With reverse snake seeding the pools look like this:

A: 1,8,12,13

B: 2,7,11,14

C: 3,6,10,15

D: 4,5,9,16

In this case, the match-ups between the second and third level teams are balanced. Let’s look at our two examples.

Team #8 now plays #1, #12, and #13.

Team #5 now plays #4, #9, #16.

The #4 team still has an advantage of playing a lower top seed, however now the match-up between them and the team below them is the same relative skill that it is for team #8. All second vs. third seed matches have a difference of 4 in seed. Of course this is worse for #5 and a little better for #9, however this is counteracted a little bit my reversing the bottom seeds and giving #5 the chance to now play #16 versus #13.

These changes, even the matches between the second and third seeds, while still maintaining an advantage for the higher seeds.
