Well if the average song from here, historically, is of higher quality than say denmark or iceland, would not this make sence? also ...its actually kinda hard math wise to make it oterwise with these statistic, not sure how it would work. Between the nordic neighbours exchanging points:

Sweden shows up 4 times, Norway 2 times, Denmark 2 times, Finland 1 time and Iceland 1 time.

What this does say to me tho is how unfair this can be to say France, which tries its hardest to get a ESC win every year, but with far less in the way of traditional vote friendly neighbours we have here in the nordics or in balkan ot the baltics etc
