A problem with introducing more poll options is that it would exceed the 10 poll option limit that some boards (like this one) impose. Unless I change the options for 2009 to be in larger increments instead of 100, like maybe in increments of 200 or 300, so in the case of the former it would be:

200 or less / 400 / 800 / 1000 / 1200 / 1400 / 1600 / 1800 / 2000 / 2200 or more

Now if I did that I would have to round off the data from this year and last year's polls to the nearest 200 for future comparisons. So the results for "100 or less" and "200" would be combined, meaning that the "200 or less" results for 2007 would be 50%.

Umm... how would I divide the 2007 "1000 or more" results into the "1000 / 1200 / 1400 / 1600 / 1800 / 2000 / 2200 or more" categories though? Or should I just leave that part alone?
