View Full Version : ACF Ratings - Improved presentation!

A few weeks ago there was some discussion about improved presentation of ACF ratings information. To show what is possible, ACE has written a system to look at recent data in different ways.

For individual ratings graphs have a look at http://www.chessaustralia.com.au/index.cfm?p=ratings

For top players by state have a look at http://www.chessaustralia.com.au/index.cfm?p=top

For titled players have a look at http://www.chessaustralia.com.au/index.cfm?p=titles

All information based on data supplied by the ACF

Neat. I like the graphs. Is this going to be kept current as new ratings are released? What's the point of making the search case-sensitive? Was it just a routine grabbed from somewhere else?

How does your graph get the discontinuity from 3/9 to 3/12?

Since the 3/12/03 figure was my first rating, the ones before that should simply not be present. Their graphing function seems to require data, however. For some reason they have chosen to use a 1500 rating instead of zero for ratings periods prior to a player being rated. It does make the graph look rather silly.

i helped brian with some of the code. yep, to update just requires to update bill's text file so should be ok if the format doesn't change too much. we didn't do case sensivity.

it's just doing query on bill's file and plotting the datapoints. however, you noticed if a period is missing we did set to 1500 (average rating) as the chart does scale badly when it's 0. will have a look to fix this (or highlight missing period) but just thought would have quick go.

Is it possible for you to (a) simply not plot data points for missing periods, or (b) have them set to be equal to whatever the first rating value is?

brian/quanta,

well done! it's got some very nice features.

one thing, though. would you guys consider making some top Under-XX lists for juniors? To some extent this is already done at http://www.auschess.org.au/ratings/, but only U12 U16 & U20 are covered. I'd like to see a wider range of age-groups put into a list so kids can see more clearly where they stand against their peers from other states.

We have changed the "no rating default" to 0 instead of 1500.
So R looks much better now!

For under-XX lists, there is no DOB on the Active List so we are looking at using the Master List instead but this is more difficult!

isn't there a dob field in the swiss perfect master list (acfmast.zip) though?!

looks like it only has the dob for juniors and top players though
(eg. one ACT player was born in 1999!!).

That is coirrect, but your use of the term master file seemed to be refering to the text file and not the SP file.

That isnt the case. It is just that not every player provides their DOB to either their state association of to the rating officers. hence many players have no DOB's listed. I know last year I added all the known NSWCA member DOB's.



(eg. one ACT player was born in 1999!!).
I'll check it out.

Excellent site Brian! This is definitely an attractive way to present the ACF ratings.

Just a suggested small improvement: when viewing rating graphs and games played over ratings periods, it would be better if the increments on the y-axis (vertical axis) were 'nicer' numbers, e.g. for ratings, if they were 1900, 2000, 2100, etc, and if for games, they were 10, 20, 30 rather than weird numbers like non-integers.

The other good thing is if you could view the rating trend over a longer period of time, but of course, you may not have access to ratings so long ago.

we've had a very quick go at top list by age at:

http://www.chessaustralia.com.au/index.cfm?p=age

the dates it's based on are not very precise (eg. 12 is dob > 12 years from today not start of year) and not displaying dob field in end result.

(also, apostrophes in the name are ignored for now. they seem to cause real havoc!)

Is it Ethan D? It's not so unusual. This is just rapid rating and ACTJCL is now rapid rating all our short time control events which includes both our U8 & U10. We have quite an active group of kindy-age players born 1998 or 1999 (born prior to May 1999 they were able to start school this year in Canberra).

It's fair to say the rating doesn't mean a lot when you're 5 or 6 but the little boy in question has won as many as 3.5 points in our events and keeps coming back!

I don't think the graph thing works for players who have moved to a different state in the time period it looks at, it only found my ratings before I moved and put everything else in as zero. I tried it with some other names of people who have moved and it works for some but not others.

the june 2005 file has been uploaded.
i can't guarentee the code/data is 100% correct
but did make an effort to make it correct.

---

with your scenario above, i can't see straight away where this would happen
but it is most likely a bug (or limitation).
i do remember there was a case where a player had exactly the same name.
i may have added a check on the state so this could mean the data series has to be the same state :(

i'll have a look next time i open up the code. i could take off the state check i guess and it would work ok.

Just a question regarding ratings - I was checking the list of ratings for active players at http://www.auschess.org.au/ratings/acfrate.htm

While the first number represents the current rating and the second number for the games played in the period, what do the third and fourth numbers indicate?

For example: 1329? 0 1377 75 Ahmadi, Mahmood

1329?= Rating (unreliable)
0= No games played in the latest period
What do 1377 and 75 represent?

Thanks!

Hi,

just to give some ideas - this is how the presentation of ratings is done in Germany (see attachments).

a) for each player one can drill into the individual results (see overview.jpg). That shows for
- which tournaments one played
- how many points one made
- what his performance was

b) further down a chart over time is shown which shows rating score and performance score

c) drilling down into an individual tournament then shows each results for all games (opponent/ opponent rating, result) - see tournament_results.jpg

Nice, isn't it?
Best regards,
Joerg

Hi,

it is presented via a website. You can have a look e.g. here (shows the members for my old German club).

http://www.schachbund.de/dwz/db/verein.html?zps=22009

The interface allows as well to hook this list in the club's website.

If there is really interest, I might be able to find out what kind of software is being used.
