Well it would appear that I have been given an award for judging honestly according to the logo beside my name. The site claims that it can identify unfair judging as well as good honest judging. If that is the case then surely it would be possible to program against dishonest judging counting for anything. Those people with dishonest judging patterns votes would just be discounted. Problem solved.
According to Brian there are millions of people voting on the Ourstage site so a few rogue teamers should make little or no difference to the outcome.
I am more concerned with the transparency of the system and the "engine" used for calculating positions. If that is flawed then it accounts for more position discrepancies than anything else.
I have been keeping my eye on particular songs that I think are either very good or extremely bad and that any unbiased opinion should spot. I have a rough idea where they stand in the category. Either my opinions as a neutral (with a badge for being a good judge) are way way off or there is something basically wrong with the system as a whole.

Despite it all Ourstage is a neat site and is worth exploring and posting material for the many reasons explained in various posts. But I do not accept that positions at any time during the month or the final positions are in any way fair and accurate even allowing for fickle public opinion.
