Wasn't exactly aware there was a rating system. Guess doing a 100 min. test in 50 minutes isn't exactly good for that. At least I should be able to go up with the next test?

akash.doulani - 2010-11-18 9:16 PMjust wanted to know how are the rating points calculated?

The rating is calculated based on a scientific algorithm (and very difficult to explain here), which uses multiple factors (e.g. scores, consistency, # of tests). The maximum possible rating is 1000 and the minimum is 0.Best way to come up in the ratings is to keep on playing regularly (dont miss the tests) and try and do well........

Akash: As Neeraj metioned, there is a currently an algorithm in place for ratings. And, we'll re-look at it periodically, to improve it further. The next review should happen around early 2011. So, if you do have any points/concerns, please share them here, so that we can discuss them while reviewing, and include any valid ones.

And, Congratulations for improving your rating by 160 points !!!

It would be nice if you add points change (for ex. +16) in comparison with score from previous leaderboard.And similar statistic for player position change :)

Fred76 - 2010-11-19 12:48 AM
Just a proposition for the rating:
It would be interesting to indicate (perhaps with arrows next to the ranking) if the rank of a player is better, worse or equal compared to last ranking (ranking before last test).

Both are valid points. This is very much a part of the plans, and you'll see this happen sooner than later.

Fortunately, the next puzzle test (FLIP) is for 50 mins duration only :)

At least I should be able to go up with the next test?

I think your LMI sudoku rating should defintely improve with a reasonable performance in the next LMI sudoku test.

And, the LMI puzzle ratings will also be coming up soon.

50 minutes for a test is an exception.
Most Sudoku tests will be between 100 to 120 minutes (ideally 120 minutes)
Most puzzles tests will be between 80 to 120 minutes (ideally 100+ minutes)

it was a pleasant surprise to see my ratings increase by 160 points. wasnt actually expecting it to improve as much as it did. i guess 360 points is not bad for someone with just two monthly tests under his belt.

Fred

I like the idea of an arrow. Maybe a green arrow pointing up and a red arrow pointing down. Lets see what we can do.
Thanks for the idea.

And Thanks to Gotroch too, for initiating the concept :-)

DreamRose311 - 2010-10-21 1:41 AMNow that there have been 5 puzzle tests, can we expect a similar LMI Puzzle Ratings soon?

Finally, the inaugural LMI Puzzle Ratings are up. You can also reach the ratings from the home page, by clicking on Puzzle under Ratings.

A total of 359 players from 40 countries are included in the inaugural LMI Puzzle rating list. Apart from India, the top five countries in terms of number of participating players are USA, Germany, Japan, Poland and UK. The LMI puzzle ratings will be updated next in mid-December 2010.

Its a neck and neck race for the No 1 spot between Thomas Snyder (motris) and Hideaki Jo (deu). Ulrich Voigt (uvo) is currently ranked third. The top 10 is dominated by the Germans and the Japanese, occupying 8 of the 10 places.

Amit Sowani, Rohan Rao and Rajesh Kumar are the top 3 Indians in the list, and the only ones in the Top 50.

Looks good. May be an explanation of what the arrows indicate?
It looks like a jump of 10+ ranks is indicated by Up arrow.

You are right. The arrows are largely self explanatory. As of now, we have used five arrows in three colours to indicate the changes in ranks, as below:

- The green arrow indicates that the player is on the up, and has made major gains (10+) in the ranks as compared to last ranking list.

- This arrow indicates that the player has made minor gains in ranks (1-9).

- The right blue arrows indicate that there is no change in the rank.

- This arrow indiates that the player has dropped 1-9 ranks.

- The red arrow indicates that the player has dropped 10+ ranks.

Thanks for explaining.
So there is no 'major' jump (in either direction) in top20.
But I would think that cpickerel and willwc cases are significant jumps.
The point i'm trying to make is a jump of 5 ranks in top20 or jump of 10 ranks in top50 or a jump of 20 ranks in top100 should be considered as major.

Blue is my favourite colour, so I wanted more of blue

.
Actually, with the current thumb-rule, it is less likely that we'll see a green or red arrow in Top 20.

But I would think that cpickerel and willwc cases are significant jumps.The point i'm trying to make is a jump of 5 ranks in top20 or jump of 10 ranks in top50 or a jump of 20 ranks in top100 should be considered as major.

I think you meant a drop for cpickerel. Thanks Rishi.
But you have got a very valid point here. Since you want to see a more colourful rating list, we can definitely think of a context based definition of 'major'. Lets have more views on this and we can refine this further.

As some of you have already noticed, the LMI Puzzle Ratings have now been updated after the two recent puzzle tests - LMI Screen Test 1 and Puzzles & Chess.

A total of 223 players from 36 countries find a place in the ratings, including 43 new players. Players who have missed the three most recent puzzle tests have not been included in the rating list.

Apart from India, there are 10+ players from USA, Germany, Japan, UK and Poland on the rating list.

The top 3 are now separated by only 20 points, comfortably ahead of the next 3.

In top 10 all players have played 5 or more tests out of 8 rated. This shows playing consistently will keep u high in the rating..........

The rating system is really cool, thanks for doing this. One issue though, on both 'change' columns, when you sort by that column, it doesn't quite sort correctly. For instance all numbers starting with 1, whether it's 1 digit, 2 digits, or 3 digits are all grouped together. (it sorta goes 1, 10, 100, 11, 110, 111)...

The sorting works the way it does because of the square brackets around the numbers.
Rakesh, any reason why the numbers have to be bracketed?

The square brackets are not necessary. They can be done away with, if that helps in sorting on the 'Change' column.

As of now, we have used five arrows in three colours to indicate the changes in ranks, as below: - The green arrow indicates that the player is on the up, and has made major gains (10+) in the ranks as compared to last ranking list. - This arrow indicates that the player has made minor gains in ranks (1-9). - The right blue arrows indicate that there is no change in the rank. - This arrow indiates that the player has dropped 1-9 ranks. - The red arrow indicates that the player has dropped 10+ ranks.

Arrows are now included to indicate the change in rank (from previous rating list). The exact changes in the ranks and ratings are explicitly indicated as well. It's great !

Thanks for explaining. So there is no 'major' jump (in either direction) in top20. But I would think that cpickerel and willwc cases are significant jumps. The point i'm trying to make is a jump of 5 ranks in top20 or jump of 10 ranks in top50 or a jump of 20 ranks in top100 should be considered as major.

Blue is my favourite colour, so I wanted more of blue . Actually, with the current thumb-rule, it is less likely that we'll see a green or red arrow in Top 20. But I would think that cpickerel and willwc cases are significant jumps.The point i'm trying to make is a jump of 5 ranks in top20 or jump of 10 ranks in top50 or a jump of 20 ranks in top100 should be considered as major. I think you meant a drop for cpickerel. Thanks Rishi. But you have got a very valid point here. Since you want to see a more colourful rating list, we can definitely think of a context based definition of 'major'. Lets have more views on this and we can refine this further.

rakesh_rai Posts: 774 Country : India	rakesh_rai posted @ 2010-12-17 11:00 AM As some of you have already noticed, the LMI Puzzle Ratings have now been updated after the two recent puzzle tests - LMI Screen Test 1 and Puzzles & Chess. A total of 223 players from 36 countries find a place in the ratings, including 43 new players. Players who have missed the three most recent puzzle tests have not been included in the rating list. Apart from India, there are 10+ players from USA, Germany, Japan, UK and Poland on the rating list. The top 3 are now separated by only 20 points, comfortably ahead of the next 3.

neerajmehrotra Posts: 329 Country : India	neerajmehrotra posted @ 2010-12-17 12:06 PM Another Observation.... In top 10 all players have played 5 or more tests out of 8 rated. This shows playing consistently will keep u high in the rating..........

DreamRose311 Posts: 24 Country : United States	DreamRose311 posted @ 2010-12-17 8:56 PM The rating system is really cool, thanks for doing this. One issue though, on both 'change' columns, when you sort by that column, it doesn't quite sort correctly. For instance all numbers starting with 1, whether it's 1 digit, 2 digits, or 3 digits are all grouped together. (it sorta goes 1, 10, 100, 11, 110, 111)...

The sorting works the way it does because of the square brackets around the numbers. Rakesh, any reason why the numbers have to be bracketed?

They can be done away with, if that helps in sorting on the 'Change' column.
