Thanks you all for your comments and the votes.
Really quite surprised this wasn't in the top five.
Well, it's all about the Maths of the voting system. As it's used a mean, my picture (and Kukucs' one) has been damaged this time:
3,36 points x 11 ratings makes 36,96 points.
The 5th place has 3,67 points x 9 ratings, that makes 33,03 points.
The 4th place has 3,78 points x 9 ratings, making 34,02 points.
But we all knew how was the punctuation system. Other times I have commented about it ; I understand the reasons and I don't want more polemics. I'll only suggest a '0 rating' because now it's better to give no ratings than to give 1 or 2 points.
One thing I can see is that there has been a very very low number of ratings: a máximum of 11 is to low for 38 participants. People don't vote... Why?
