Betting Forum Polling Capabilities

[yinyang]

I'm thinking about starting a forum based around sports betting. What I want to know is there a way to do this and the entire form will be very Poll oriented.

For example, there will be ten NFL games during the upcoming week. We poll who the members think will win. Is there a way to compare actual results of the games with the poll results?

i.e., a member voted on 10 games and he was 50/50. is there a way to show in the post bit that his average is 50% winners? then if i have different forum for different sports, his post bit will show his winning average for all the different forums/sports.

Then i'd like to be able to compare the results of each Poll as a whole to the actual result. Thereby providing a community winning percentage.

My question... who here thinks this would be easy to modify and who here thinks it would be hard?
