Opportunity Matches

EVSTL Captains & Players,

I am the 2.5 captain for Leisure World.  I was looking at this week's Opportunity Match (OM) spreadsheets for all the levels and noticed some interesting things.  

Here is some basic information to give players a better understanding of OM's:

The OM spreadsheets are a tool for captains to use to get extra players on the courts.  OM's serve a dual purpose - Captains can enter pairs of extra players or enter requests for pairs to fill lines for league play when one team has more lines than the other team.  After noon, two days before league day, the OM Coordinator for each level first tries to fill the vacancies for league matches, then sets up matches with the remaining extra pairs who will play at a predetermined site.

This morning when I peeked at the 2.0 OM spreadsheet, there were 15 teams placed in vacancies for league matches, and 4 OM's being held at VP this week.  This process has allowed 76 players to play this week who normally would have had to sit out.  That's amazing!  Kudos to Brenda Wile from CM who is the 2.0 OM Coordinator!  

I have 27 players on my 2.5 team (17 men and 10 ladies) and none of them have had to sit out this season because the 2.5 captains are utilizing the OM spreadsheet.

I was very disappointed when I opened the OM spreadsheets for 3.0, 3.5 & 4.0 levels.  I saw a lot of empty spaces, which means that players are sitting out.  Perhaps these captains can delegate this duty to another person in order to get more players on the courts.  It is very simple to access the spreadsheet and enter teams.  I have documents with step-by-step instructions that I shared with our LW captains and the other 2.5 captains.

The OM spreadsheet would address a couple of issues for the 4.0 league. The EVSTL board proposed a future 4.5+ league, which was voted down because most of the 4.0 players who would be affected want to stay with their teams.  There are also some 4.0 teams who have 2 teams but only one roster and this hasn't worked out very well for some of them.  The OM spreadsheet would solve both of these problems.  If one team has players with really low Tencaps that the other team can't match, they could request a team to play against the low Tencap team, or enter this team as extra players to be placed in another league vacancy or to play in an OM match against another low Tencap team. (This scenario happens at other levels also.)  Also, if one team has more lines than the other team, these players can be entered as extras on the OM spreadsheet to be placed in league vacancies or into OM's at the predetermined site.

If teams have players who are sitting out every week, they could be utilizing the OM spreadsheet to get as many players on the courts as possible.  If you have 2 teams at the same level and each has an extra player, these 2 players from the same resort can be entered as extras.  Let's work together to get as many players as possible playing every week.  We have proven that it really does work at the 2.0 and 2.5 levels.

Let me know if you have any questions.

Thank you,

Rating Trend

We have had a few questions about matches where ratings did not appear to move but you played better (or worse) than system expectations.  Your rating is recalculated after every match and it does move fractionally but you do not see that level of detail unless the adjustment crosses the rounding factor.

For instance a rating of 49.3 may adjust to 49.1 after a match.  Both ratings round to 49 and that is what shows under “My Dashboard” in your rating badge.  But there is one signal that let’s you know your rating is changing.  Just under your rating, in the rating badge, is a slide with a tennis ball in the middle.  If a green arrow shows to the right of the tennis ball that means you played better than expectations in your last match.  If a red arrow shows to the left of the tennis ball that means you played worse than expectation and your rating moved fractionally higher.

It is a level of detail that does not matter much but for very detail oriented folks it does offer a rating trend.

What is with my rating?

The number one complaint I received last year at this time was the excessive movement of ratings after a match.

The number one complaint I am receiving this year is the lack of movement of ratings after a match. 

Higher confidence levels will begin to slow down the movement as the system gains in the number of matches to build a very good history.

“Official” means your CL is 90% or over.  Once you get close to 80% or more, the system makes smaller adjustments either way because it has a very good history of your playing level. 

People also ask why their rating didn’t move after a match.  Ratings are recalculated to multiple decimals after every match, but they are rounded to the nearest whole number.  It is possible for a player to have 9 tenths of a point of movement and not see a whole number rating change.  For instance: Player A is rated at 49.4 (49).  After a win the player gets the benefit of a 0.9 improvement in rating to 48.5 (49) which rounds to 49.

The biggest point we need to remember is the importance of the accumulation of matches.  Look at your last 5 or 6 matches.  Has your rating improved from 5 matches ago?  If you are improving a few tenths each match, you won’t see it weekly, but they all add up showing that you are playing better than the expectation of your rating, which means your rating will go down.

On the other hand, if your rating has become higher over the last 5 matches, you know that you have not been playing as well as the expectation for your rating and your rating will move higher. 

But the most important point of all is that we have 10 more matches this season in which we can play and have fun.  Focus on the Fun.


How will a BAD MATCH affect my rating?

There is still a great deal of misunderstanding about what happens to a rating when a player has a bad match.  First of all, we all have bad matches and that is part of the game.  It always has been.  But let’s show an example of what the system does in subsequent matches after a person has a “bad match”.

Assume a person plays like a 45 rating, but a very bad match takes them to a 50 rating.
And let’s also assume the next match is against a team that is also rated at 45.

For the player rated at 50, the system expects much less from them than it does if they are rated 45.  It expects a result of approximately 4-6 and 3-6 or a 5 game difference.  Assuming the player actually plays like a 45 the final score will be 6-6  and 6-6 or no game difference.  That means the system will improve the rating for the person with a rating of 50  and move them a point or two back toward their actual playing ability.

BUT, if that person has a rating artificially set back to 45 after that bad match, then the system would expect the player to win at least as many games as the opposition.  So a 6-6  6-6 score would net the player ZERO movement.  And if they lost by a few games, their rating would get worse.

The system always moves the player toward their actual playing ability.  Resetting a rating after a bad match was never done in the old EVSTL system. It is not done in the USTA system and it really isn’t necessary in the Tencap system.  In the example above, a player can move back to their actual playing ability in just a few matches.

It works the opposite way as well.  If your opponent has a very bad day and you gain a “windfall” of a rating improvement, the system will move you back toward your actual playing ability and you will find your rating will get there much faster than you desire.

Team Captains: Adding temporary (Substitute) players to TenCap Roster

To: All Team Captains

Captain Procedures states:

6. Captains should designate borrowed players or play-up players as “substitutes” on the roster, and remove the “substitutes” following the match to maintain the team roster as accurate as possible unless certain players have the opportunity to play up often.

Please designate them as "substitutes" and not "player"
