Thanks Colin. I did some mental arithmetic a while back and came to the same conclusion. I have been saying that the system is flawed from almost day one. I have come in for a bit of stick from people who have not really thought this aspect through. The figures speak for themselves. It is hardly surprising that songs end up in wrong positions when even the basic principles and figures do not pan out never mind cheating or bad algorithms.
Put simply it is like a jigsaw puzzle with most of the pieces missing you only get to see some of the picture.
I rest my case.

That said Ourstage is a great site but results and judging IMO mean very little.
