Title: Seeding groups in a mini tournament.- more fun, fewer walkovers
Post by: Fred in Sweden on June 10, 2019, 06:11:08 AM
Hi,
I’m super excited to have found you guys. If there’s anyone out there that can help i'd be super grateful, I would even make a charitable donation to a cause of your choice.
Thanks,
Fred

Summary:
I would like some help setting up the first stage of a mini tournament in such a way that pairs up players with a mix of different partners and opponents at differing quality levels, based on seeding. This way, it’s much more fun for everyone.
I would need 1) lists of who plays with who, and against who, and 2) a list of which matches are happening in which order, based on us having 2 courts available.

More detail below

Background
We are having a one-day mini padel tournament this coming Saturday 15th June. 
Padel is always played in pairs but our group of 12 players does not have fixed pairs. We mix and match. There is a large quality difference between the best and the worst and it could be very boring and unfair for some, e.g. if we draw lots for partners and the worst two players end up a team together and lose every match. So we want to pair each player differently for each match, and as far as possible, each team would face opposition of broadly similar combined quality balance. So, basically, an even mix of quality of both partners and opponents would mean that every match is more competitive and hence, way more fun.

We can split the quality levels into tiers and seeds.
There are 12 players and 3 tiers
Let's call the top, best group the A group so they are  A1, A2, A3, A4.
Middle group of ok players is B5, B6, B7, B8.
Bottom group of weaker players is C9, C10, C11, C12.

The format of the tournament would be in two stages:
Nine matches in stage 1 and Three in stage 2.
Each 'match' consists of one set and lasts around 20-30 mins.
Scoring is like tennis, so the possible results each match could be 6-0, 6-1, 6-2, 6-3, 6-4, 7-5 or 7-6.

Stage 1:
Each player plays three matches comprising one ‘set’. (this is not an ‘everyone plays everyone else tournament – no time for that)………..and here's the challenging bit:
I would like to set it up so each player gets to play:
One match with a partner from Group A against opposition of broadly similar combined quality levels
One match with a partner from Group B against opposition of broadly similar combined quality levels
One match from a partner from Group C against opposition of broadly similar combined quality levels
I've tried working this out with pen and paper and get nowhere.

Stage 2 is more straightforward:
using a points system, I’d work out total points for each player as follows:
Points are calculated for each individual, not for each pair.

Each player scores the number of games won plus 2 points for a win.
So, for example, if A1 and B5 beat A4 and C11 by 6-2
then
A1 scores 6 + 2 = 8 points
B5 scores 6 + 2 = 8 points
A4 scores 2 points
C11 scores 2 points

All points will be added up and a list made of the top 8 players.
Then the pairs will be fixed as follows:
1+8
2+7
3+6
4+5

the semi finals will then be
1+8 vs 3+6 and
2+7 vs 4+5

The finals will be the winners of each semi final.
