Well, my map is based on my own statistics. Basically I rank the countries based on the average score they have collected up until now from contests between 1956-2012. The average has been calculated out of my own personal rankings by counting the combined points I've given out for each year's edition (I made a top for each year and given out pts ESC style) divided with the total years a country has been taking part. So for instance I've given Israel a total pts of 189 between the given years and the country has taken part 35 times, so its average pts ends up at 5,400.
I don't wish any current participating (or country that has been participating in the previous years) out of the contest, so the lowest score they could get here is that "I don't like them". Also in the "Bring to the contest" category, I put countries that either haven't taken part so far but that I want to add to the contest (Kazakhstan & Liechtenstein), or that haven't taken part in a very long time but I want to return finally (Luxembourg).
So this what my map coloring is based on:
Average pts:
0,000 - 0,999 : I don't like
1,000 - 1,999 : I don't like so much
2,000 - 4,999 : Country I like
5,000 - : Country I love
As for microstates:
Don't like
Don't like
Don't like
Don't like so much
Bring them (back) to the contest!
Bring them to the contest!
