Also, your own username is highlighted with a pale yellow bar if you've completed a puzzle in this way.
I'm glad you like it. The next step is to do a ranking chart for each puzzle type, so you get the average time over the most recent (say) 5 or 10 puzzles of a type.
If anyone has any other suggestions for ranking tables please let me hear them!
Another idea would be to have the 'best overall' for someone who completes all the puzzles on a day, except that's quite a high bar and some days I suspect almost no one will do all 4 puzzles without the aids (say if there's a 12x12 wraparound sudoku or something). It could be your 'best 2' puzzles but then that gets complex to define and I'd rather keep it simple.
Oh, and I still need to make the site keep track of whether you've opened a puzzle more than once. If you opened and closed it then it shouldn't count towards the chart unless you complete it on your first opening.
Like: I solved 4 kakuros.# my time, average for the puzzle, my %#1 2:00 1:00 200%#2 1:30 1:00 150%#3 4:00 3:00 133%#4 6:00 10:00 60%
Average time:3:22 (pretty meaningless)Average of averages: 3:45My average against average of averages: 90%My average percentage: 136%
Of course it might happen, that you have to leave your puzzle before finished, and forgot to save it. Or simply did not have the opportunity. So worst 10% could be exluded from the calculation. Or something like that, to prevent a 1536% kills your average.
I more thing: all time played would be interesting, however it has a chance to scare people. :) "OMG, I could have changed the world during I played puzzlemix." :)
I would also love to see number of puzzles I solved fastest.
Your system allows the ranking to be independent of the puzzle selection, but that wasn't what I had in mind. That's much more of a universal ranking system, which I think is something else again - and definitely something I'm interested in doing, so I'm not dismissing that at all. For that to work the rankings would need to have a rule along the lines of "you must play the puzzle within 48 hours of it being published" and then the scores would be frozen at that point for that puzzle. Otherwise it would be too computationally expensive (to redo all calculations every time someone viewed the page).
I don't keep total time for all puzzles, particularly if you played the puzzles more than a year ago when I periodically wipe your data for expired puzzles, and if you played more than once. However just for you, kocos, I can tell you the sum of your most recent solve time (so ignoring any prior plays of a puzzle) for your puzzles I have in the database still is 218 hours. And yes, I don't want to scare people! I've considered that sort of stat before but I think it is more off-putting than helpful.
Here is an example. You write to test on the same subject. One of them has a maximum of 50 points, while the other has 100. Your result on the first one is 50 points (100%) and 60 points on the second one (60%). What percentage discribes your knowledge better? Sum of scores against sum of possible scores (110/150 = 73%) or the average of your percentages ((60+100)/2 = 80%). My vote goes to the second choice.
One more thing: you only have to recalculate results when a new (first) suolution time arrives. A simple view does not change the numbers. Considering this I would not froze the averages at all.
Gareth: could we have something like that in the future?
