Thanks for bringing this point up, James.

Wow, I see William Blatt jumped up 10 places from 24th to 14th. And he didn't even compete!

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.

You can make a similar argument for Neil as he only has 4 tests. But because two of his tests are marathons, where the PS is much higher for the top puzzlers compared to other tests, his rating average is much better.

Hello,
There has been a lot of sudoku tests these times, but few puzzle tests ( only Pentoparade in october and Forsmarts in december ).
Can we know when the next puzzle tests are planned ?

Also, for authors/testers, I think NumTests should include the tests they authored/tested.
For calculations, it should be ignored.

So,before the ratings get updated after Round 2 of PR , I wish to state here an observation and a rare coincidence . My current LMI Puzzle ranking(133rd) and LMI sudoku ranking(38th) are exactly the same as my position in WPC(133rd) and WSC(38th) 2016 in Slovakia respectively !! :)
