Once you start participating in the monthly tests, your ratings will appear on the ratings page. As of now, there is no Monthly Test announced because the Indian Sudoku Championship is the next event being held here. But stick around and there'll be a monthly soon.

I was just thinking that Is it possible to rate Teams (Countries) as explained below

1. Sum of top 4 four players from a country will be considered their Team score.
2. Score of Players from the same country who are not in top 4 will be ignored for team score.
3. For the countries where less than 4 players participate, sum of their scores will be team score. It will encourage them to get more players from their country to give test to get better Team ranking.

This is just an idea. First thing is that this should be technical implementable easily. If yes, we can discuss further on this or may be start a new thread.

I have a suggestion regarding the "pink table" on profile pages. Can it be moved to a new page, that also lists the values of N, L, U, K, Kp, and which tests are considered and how much weight for each (like Player C in the sample)? It helps cleaning the somewhat cluttered profile page, and it can display more information. In fact, if my assumption of how the table is displayed behind the stage is correct, the new page can simply have a copy of the current table, and the current profile page can have the last four columns removed. The main task would be to display a new "weight counted for the rating" column, plus computing N/L/U/K/Kp values.

^ Yeah, mostly because of laziness computing by myself.

Sounds like a good suggestion; so will get it done. It might take a while, because not all information is handy in the database.

In the meantime, ratings updated after ST4 and deu continues his top rank.

On the Road to London topic, there's a notification from the Admin that it'll take a few days.

New puzzle ratings are up after the Pento Parade test.

Wow, I see William Blatt jumped up 10 places from 24th to 14th. And he didn't even compete!
(Arguably) if he had competed he might have got a lower rating, because this test had a top score well ahead of the main pack, which means everyone gets a lower score than they otherwise would.
As discussed for other competitions, basing the score for the top half of the field on the overall best score gives a wide variety of results, meaning different tests get different distributions of final scores.

Thanks for bringing this point up, James.

Yes. That's correct. Ratings can increase if (a) you do very well in the most recent test, OR (b) you had a bad performance twelve months ago (which goes out of rating calculations now) but have since done ok. Generally, we tend to correlate rating improvement with the first of these reasons, which is natural but not a complete view. LMI Rating system (Puzzles) takes into account performances over the last 12 rated puzzle tests, which roughly means twelve months. William had a (relatively) lower rating so far because of his (arguably) inferior show in the Forsmarts Anniversary contest 2013, where he was ranked 37th out of 108 non-zero scorers. In the latest ratings, he got rid of this baggage. And due to relatively stable performances over the last twelve months, his rating has improved and come close to his actual recent performances. I would say, "the rating system waited for a fair number of improved performances before registering an improvement." And, since he has not been a regular participant (yet), the rating has potential to improve further. I can see some analogy to FIDE ratings (chess), where it takes time to reach your actual rating levels.

(Arguably) if he had competed he might have got a lower rating, because this test had a top score well ahead of the main pack, which means everyone gets a lower score than they otherwise would.

Your argument is valid since willwc has played less tests in the recent twelve month period. For a more regular player, this argument is not valid. For example, if he had performed as well as you did on Pento Parade, he would have still reached a rating of ~833 to be 17th, a jump of 7. And, if he had got more than ~1140 on Pento Parade, he would have bettered a rating of 845 also. But, in general, yes, NS on this test would be lower because of the exceptional top score.

As discussed for other competitions, basing the score for the top half of the field on the overall best score gives a wide variety of results, meaning different tests get different distributions of final scores.

Agree with your point. This point has been discussed while devising the ratings formula. Also look at this post from motris summarizing the discussions around this. I am not saying we cannot make changes. But "Is an improvement needed for handling such tests with outlier performances?" is the question.

Also, you can refer to this earlier post. In the example, player D resembles willwc. So we take a straightforward weighted average of his NS to get to his rating.
