XG's vs Rank

SnippetSnippetNow that XG's have been with us for a few months and some 40% of players are progressing from Evolving (less than 1000 boards) to Mature status it seems timely to look at what sort of numbers our higher-ranking players are coming up with. The spreadsheet attached below clearly demonstrates what we all suspected .. top players have top XG's.

The population of 3116, sorted by XG Rating, was divided into 31 bands of 100 players of X-Club deals. Because some of the ranks had small numbers - eg 44 Life Masters vs 1375 Local Masters, the raw numbers would mask the point of the exercise. The chart is presented as the percentages of each rank falling into any particular band. A sample of how to read the chart might be: 50% of the 52 Grand Masters who play X-Club deals have XG's in the top 100 band: 15% in the second band of 100: 12% in the third etc …

Other observations:

  • One third of NZB-affiliated members play X-Club deals
  • Only 40% of these 3116 players have XG's over 50 which translates to 40% have negative handicaps while 60% have positive
  • XG's for top of the table exceed straight averages by some 5%, about equal for middle of the table, 5% lower near the bottom of the table. This seems to indicate that handicapping by straight average (as clubs commonly do) favours the stronger player

Have a look .. it's interesting

A Bit of an Analysis

Following on from a casual question this extract was taken from the Results pages. (Hope we haven't missed anyone - please let us know)

In case you're wondering ..

.. Bob has added another column to the Ladder - XG Status. The three categories are Unpublished (U = played < 150 boards), Evolving (E = played between 150 and 1000 boards) and Mature (M = played > 1000 boards). This is because it takes a while for the XG's to settle down - see graph below as an example. Thus, a reasonable player who is status U has a good chance at coming top on the Handicap as their XG will remain at zero until they get beyond 6-7 sessions. Only the most recent 2000 boards are taken into the calculations.

Remember .. all the columns in the Ladder may be sorted by clicking on the green column headers.

Putting the Babich to Bed in 2018

By midnight Friday we had 50 clubs

WELCOME, NEW ZEALAND, TO THE HOME OF X-CLUBS

Did you know that X-Clubs deals are being played in just about one third of New Zealand's clubs? It's like you can have a mini-NZ-Wide Pairs every time you play at club. Check out our Results pages to see which clubs are involved. But that's just the start! James Ward, founder and CEO of Pianola has generously allowed us free use of his fantastic results reporting service. All you have to do if your club plays X-Clubs deals is to send in your email address from this site to get a personalised invitation to create a Pianola log-in for yourself.

We are very fortunate to have a regular commentator on X-Club's Wednesday Night deals. Vil Gravis is an author of long standing and we are privileged to host his lifetime's articles in pdf form on this site. Click on the Vil's Books tab above to see for yourself.

The 2017 Babich NZ-Wide Pairs was scored using Bob Fearn's Compass scoring program: the power behind X-Clubs. We had the first cut of 50 clubs out by midnight. The remaining nine results were in by midday Saturday allowing us to create the final reports for the 1018 pairs that took part - the largest number in many years.
