TOURNAMENT SEEDINGS “How’s it work ?”
Comments From Brian Davey – MARCH 2003.
It was
approximately a year ago, Duncan Constable and I had been
progressively developing a player-ranking database for use when
seeding tournaments. I decided to try an experiment and distributed
a list of our top twenty ranked players in ranking order from the
database and gave it to eight players who were either in the top
twenty or had played against the players in the top twenty. I
invited the eight players to return the list to me with their own
ranking order, the outcomes were: -
- None of the
eight players agreed with our list from the database and,
- None of the
eight players agreed with each other and,
- Six of the eight
players ranked themselves higher than what the original list had
them.
My takeaway was
that you will never please or get agreement from everybody about
this and secondly, we needed to ensure that our database was
influenced by some logic and not peoples opinions.
Since then, Duncan
and I have put a considerable effort into improving the database and
make it a workable tool that is effective in ranking our tournament
players, we believe that we have progressively been achieving that.
The purpose of this article is to offer you an explanation as to how
some of the rankings and matches happen at the respective
tournaments, and also offer you a partial insight into the variables
we have to consider and some we don’t consider.
During the article
I will often refer to “we”, that being Duncan and myself, it is
worth pointing out that Duncan voluntarily contributes many hours
into this, he is continually maintaining and making enhancement
improvements to our database that also executes the tournament draw.
Effectively, we
have a database that has 386 active tournament players on it. Each
player is ranked from number 1 onwards, and this is adjusted after
each tournament after consideration of the results.
It is often
commented that we should include pennant results in our rankings; we
don’t for the following reasons,
- Pennant grades
are ranked by the team members as a collective, not as
individuals, it is not uncommon to find stronger individual
players in lower pennant grades, and equally not uncommon to
find less stronger players in higher pennant grades. The upshot
of this is that the individuals rarely, if ever play each other
in pennant, yet will cross paths often in tournaments.
- Of the 816
players who play VMSA pennant, only 210 of them are regular
tournament players.
- The standard
difference between competitions is a constant variable we can’t
monitor, e.g – Grade 2 in Bendigo midweek is not as strong as
cup grade 2 in VSF. Also, some pennant competitions have
handicap scoring. Our current crop of tournament players compete
in, VMSA, State grade, VSF, SSL, North West, and several
regional pennant competitions, it would be huge task to monitor
the results of all of these pennant matches each week.
Some of the pennant
competitions have allowed us to have team entry copies, these are
used as a reference, however, pennant results have little if any
impact on our ranking list.
It is often
commented that, I was in section 3 at Sale, which I won a trophy in
and now I have gone down to section 4 at Ballarat
- Unfortunately,
it is common for most people to interpret a section as a grade,
IT IS NOT ! Each section is a group of sixteen players. Section
one is the top ranked sixteen players that have entered that
appropriate tournament, section two the next group of sixteen
and so on.
- The more players
that enter a tournament, the higher the section number you will
be grouped in, (unless you are ranked in the top sixteen
players). I will use myself as an example, my ranking number in
99, if every player on our ranking list entered the same
tournament, then I would be in section 7, (99 divided by 16).
Generally speaking, I play in either section 2,3 or 4, which is
determined by the number of entrants.
- Using the recent
Sale tournament as an example, I was in section 3, My grading
number is 99, and I was seeded at number 1. The number 16 seed
in section 3, had a ranking number of 129, again the number of
entrants determined this. At the Ballarat tournament, due to the
large number of entries, I would probably be a lower seed in
section 4. Unless I improve my ranking from 99 between now and
then.
Gee, Brian is
seeded at number 5, above Ray at seed 9, yet in their pennant team,
Ray is higher, how does that work..
- The major
contributing factor to these anomalies is contributed to by your
availability to play on a Friday night. It is critical that the
tournament completes at least 55 matches on a Friday evening,
due to the fact that not all entrants are able to play on a
Friday evening, we adjust some of the seedings to accommodate
players who can play each other on a Friday, and players who
can’t, play each other first thing Saturday.
- We still have to
factor in times, some players can arrive at 7.30 pm Friday, some
at 10.00 pm, hence the alterations. We only make these
adjustments within a section.
- The other
frustration is some players pull out of the tournament at the
eleventh hour; this is almost impossible to cater for. The
regular offenders of this practice have been noted.
We do consider
players returning or recovering from injury, or who have not played
for a while, however, if you are in this category, it is critical
you advise us. The most effective way to do this is to note it
on your entry form. We also watch as many matches as possible, so as
to familiarise ourselves with who is who and who is hitting the ball
well, or not so well. Unfortunately, we don’t consider the toll you
may place on your body during the course of a tournament,
self-inflicted performance dehancenet activities are your choice.
Don’t try to kid us on this one, Duncan and I are the experts in
this area !!!!
A measure that we
have applied to ourselves is to monitor the number of second round
matches that have a 3/0, 3/1 or 3/2 results, regardless of whether
they are a main event or plate event. We are noticing a decrease in
the number of 3/0, second round results, which indicates that the
matches are more even; therefore the rankings and seedings are
having the desired effect.
The RANKING –
the whys, where-fores, what ifs, butts and maybes.
Contrary to some
players opinion, the tournament ranking process is not governed by
the laws of witchcraft or astrology. Detailed below is a commentary
to explain how the performances of a player is accessed at a
tournament. Each player that enters a tournament has a ranking
number, and that is adjusted after each tournament they play in. If
a player does not play a tournament for two years, his name and
details are archived, should they ever play another tournament,
their ranking will be updated after considering current details. We
make a similar consideration for players who may be returning from
serious injury. In any individual tournament, players are sorted
into sections of 16 players (assuming there is sufficient players in
quantity and standard to fill that section, otherwise a smaller
group is formed.) The first round matches are played from a higher
seed v lower seed key:- Seed 1 v 16, seed 2 v 15, seed 3 v 14, seed
4 v 13, seed 5 v 12, seed 6 v 11, seed 7 v 10, seed 8 v 9.
Each player is
rewarded for their wins by allocating points in accordance with the
table below:-
|
EVENT |
POINTS per WIN |
| |
|
MAIN |
|
5 |
|
SPECIAL PLATE |
2nd Round Loser |
4 |
|
PLATE
|
1st Round Loser |
3 |
|
CONSOLATION
PLATE |
1st Round Plate Loser |
2 |
At the end of the
tournament, a players ranking is adjusted (higher or lower) and the
following criteria is factored into the adjustment.
- The final
placing (1st to 16th) as determined by the points per win
allocation.
- The strength of
the section, which is determined by the gap between the ranking
number of the highest and lowest ranked player, i.e.:- Player
seed 1, is ranked at 60, player seed 16 is ranked at 110, the
gap is 50 ranking places (110 – 60 = 50). This gap number is
divided by 16, and becomes our weighting factor for that
section, in this example the weighting will be 50 divided by 16,
which is a weighting of 3.1.. This figure is applied to adjust
your ranking up or down by 3.1 places subject to where you
finished in the section.
- Points won from
a walkover are not considered when we make a ranking adjustment.
- Some basic
common sense……. Yes Duncan and Brian do have his capability.
By considering the
criteria above, we seek to “smooth” the changes in rankings and
hopefully allow more competitive and enjoyable matches.
In closing, can I
invite your comments, it is important that we know how we are doing,
and what you are expecting. Remember, a tournament is about good
squash, good fun and good friends.
Yours in
squash…………………….Brian. (Mobile 0417394314 / Home 95463078 ).
