Back home and just woke up from sleeping 13 hours. Still very tired. Can't say enough how happy I am to be back.

There are some official "results" at the W "S" "C" website, but some things are still missing. They did officially remove Maki Kaji as a listed guest. Turns out in the last week both Wayne Gould and Maki Kaji pulled out for different personal reasons. I wonder if they also managed to sense ahead of time how bad things would be as it would have been a dishonor to have them there.

Now that I can actually see the listing of finalists, I can tell you the individual qualification ranks and names of the finalists which never made my report. Jan Mrozowski was on my short-list of potential winners given his online performances before this year (he was a strong competitor who couldn't travel to Goa as well), so at least a possible contender emerged from this chaos with the "title". Still:

1st - Jan Mrozowski (POL - 4th - 231 points)
2nd - Branko Ceranic (SRB - T28th - 161 points)
3rd - Robert Babilon (CZE - 30th - 160 points)
4th - Nikola Zivanovic (SRB - 11th - 207 points)
5th - Mehmet Murat Sevim (TUR - T9th - 209 points)
6th - Sebastien Leroy (BEL - 33rd - 153 points)
7th - Ko Okamoto (JPN - 36th - 149 points)*
8th - Goran Vodopija (CRO - T28th - 161 points)

Then the official rankings list me as the best non-finalist:
9th - Thomas Snyder (USA - 1st - 265 points)*

* Ko Okamoto eliminated me in group A by submitting 3 answers at 31 points with 2+ minutes on the clock. I was 2nd in the group at the same score but without submitting. So, 36 slew 1. Of course, others then broke the tiebreaker for the open spots, but this was the group spot I should have won.

In other words, the finalists were 4,9,11,28,29,30,33,36. The average rank of a competitor after the semifinal was 22.5, 4 spots worse than the 18.5 it started at. The median at 28.5 suggests the top solvers that got through were the outliers in a long tail and not the other way around. This is a problem. Unless you believe, like our parents do, that we are all champions.

Some people on the Times (of London) comments side wonder why I would rather have them playing poker for the final as poker is a game of skill. Well, at least then everyone would have a fair shot. This set-up penalized good solvers and did not care about it at all. Harrumph. If you read that piece, you can see me in my finest. My basketball analogy was specifically for the lunacy of the format of the final puzzles (on massively large grids that some competitors struggled to even reach the top with) but it can apply to the whole thing I guess.

Some corrections since print journalists never get things right: I never had the 5:25 world "record" that was set at the Slovak National Championship last year. I was not there. I had two records on easy and very easy puzzles between 1:30-2 minutes in time that actually weren't easy/very easy enough as I can be under a minute even on a 30-31 given puzzle. Also, a Latin Square has no diagonal constraints. It is correctly mentioned that Latin Squares are not Sudoku by Tom Collyer.

At least the "championship" can be summed up by something said by the man who survived the process. Jan Mrozowski put it this way: "The last puzzle was very hard to work through logically, so I made a guess at one point. It was wrong, but I was able to go back and change it, and the answer became clear.”

Maybe Crook's method is the way to go in the future then....

Submission time should only have been considered when multiple people solve all the puzzles (which no one did). Otherwise, the primary tie-breaker would have been the contestants' ranking after the preliminary rounds, giving an appropriate reward for earlier work.

If that had happened, then the finalists would have been those ranked 1,3,4,6,9,11,13,33. Compared to the list above this looks much more reasonable, while still allowing for someone to perform brilliantly in the semis and rise up from the depths, as was done by Sebastien Leroy.

That being said, a semi-final that takes 30% of the competitors, and otherwise ignores the preliminary round results, is somewhat silly. Thomas could have quit at 11am (after only the first round) and still made it!

In the WPC Rio semifinal before final, the ranking was also done on order of finishing puzzles, but the puzzles were graded on the spot so solvers could be judged on who reached 5, 6, 7 done of 7 fairly. No one finished that round, but an order based on when 6 was reached separated the two Japanese and then on when 5 was reached separated me, Pal, and Ulrich.

When you reached 3 of 4, not when you stopped, would have been an acceptable standard had it been used.

Hehe, see below. That's what I get for slow posting.

And of course, that Rio playoff also had a staggered start so I would have had about 5 minutes extra on 2nd if that was used here, but I'd settle for just some and not all improvements to make a WSC like a WPC.

Btw, why not rate it like...Thomas has 3 puzzles done *by 29:30 on the clock*, so that's his official time; when did you finish your last puzzle, and how many points did you have when you did? I think that's what Jan was trying to simulate here...but botched it entirely.

Maybe you could even have some sort of real-time grading thing? You finish your first one, raise your hand, they collect it, and you get rolling on your second one; if they find an error, they give it back to you with a one-minute penalty? I dunno...but there are ways to make this sort of thing work.

Although, as best I can tell, anything that only "rewards" the #1 solver by giving him the edge in a second-tiebreak (that almost certainly won't matter) is a dumb system. And I really don't think the point-lead -> time-advantage method is broken anyhow.

No matter what -- we should've been notified of whatever format it was going to be (good one, bad one, poker one) well in advance. But you knew that.
