OK here is something interesting. Sort of related.
Last year Tom Hislop had donuts
http://www.finalsiren.com/PlayerStats.asp?PlayerID=1766&SeasonID=2008
His game in round 10 lead to his average being 38.3. He was subsequently priced for 2009 at an average of 38.3....an average which included the zero, even though it was a complete donut game. No stats at all.
Same happened with Demspey last year, he played 4 games, 82,28,72 and then a 0 with no stats. His end of year average was 45 which was his price this year.
