Sorry if it is explained somewhere, but I could not find the answer for this in the forum search function, so here goes:
How is the poll results calculated? Is it a simple add the numbers selected and divide by the quantity of votes?

If so, then it will be true that if 10 people voted on income on site A as follows:
2 people = 1
5 people = 2
3 people = 9
Then (2x1=2) + (5x2=10) + (3x9=27) = 39 / 10 = 3.9
10 people voted on income on site B as follows:
5 people = 3
6 people = 4
Then (5x3=15) + (6x4=24) = 39 / 10 = 3.9

A and B score the same, yet B's income will satisfy a higher % of contributors.

Yes it is a simple calculation like you say.

The biggest problem comes from the numbers averaging together the same when their values in terms of $$ are not the same.  The overall results I believe is accurate though.  More people earning over $1000 on a site gives that site a lot of 10 votes.  I think the main difference, if the average was calculated from the $$ and not the 1-10 numbers, would be a greater split between the  Big 4 and the rest.  I plan to update how the polls work relatively soon.

In your example though, I would rather submit to site A where people are actually able to earn a decent income... that said it would be interesting to know if certain sites have a bigger spread than others meaning it probably favors one group of photographers more than others.

Maybe, i the mean time, if one can know what % of votes on each site where on 1 and maybe 2, it will give you a very good indication of income spread. Will help a lot in evaluating the sites' strength and exposure?
