I don't have record for my earlier votes, but starting with 2016 there are the results:
Russia is the only one to score twice 12, Brazil got 4 medals in total, Denmark is the most consistent - the only time they didn't get points was the time they won! Slovenia is on the rise having scored consistently in the last two years. Lithuania is the only one with the full set of medals and total of 38 countries scored! Malta was awarded points at 5 out of 10 editions but four times it was 1 point only! Poland, the regular participant scored only once and it was 12. Czechs being quite irregular got points for the very first time this year. Some of the regular participants that are yet to score are USA, Germany, Slovakia, Romania, Bulgaria, Greece.
