I've finished going through every
single answer key that was submitted(!)
A list of answer keys, and points allocated thereto can be downloaded from here
, if you want to check for fairness and consistency.
I felt that some leniency should be allowed for some puzzles, as well as the normal recognition of obvious typos.
The way I did it was:
1) I ran a database query that selected all distinct answer keys for each puzzle with a count of how many times each was used.
2) Compared every entered variation with the correct answer, and with the puzzle grid.
3) In 2 cases, people entered the wrong row or column. I awarded 1/2 marks for those two, since it was an obvious accident.
4) For puzzles where excessive counting was required (1,8 & 9), if there was a SINGLE counting error ONLY, a small penalty was incurred [#1: 3 points awarded; #8/#9: 10/15 points awarded]
5) In cases where the puzzle has been solved 'beyond reasonable doubt', and it is clear a single typo has been made (or answer key misinterpreted), I've awarded 2/3 marks (rounded up to next integer). Those cases are clear in the above PDF.
I did this all completely blind. I believe this is completely fair. I have no idea who I affected, so apologies if your score has gone down, though likely upwards. Nor in the end did I take any heed of any appeals. To do so would distort the fairness of the above systematic analysis.
Boy, am I going to make the answer keys more simplistic, and I won't be so forgiving, next time!
Puzzle Cruise is 2-3 July!!! See the main Contests page
The results table looks slightly different from usual - more LMI format. You should be able to click through to see each participants entries.
(red answer keys are too wrong to gain credit, green is correct, orange is partial credit)
Results will automatically appear on the contest page at 3am (just in case I ran late here)
