Some time** ago i was following a couple of chaps on a UK forum re handicapping. One of them posted a link that produced a booklet re barrier bias. I downloaded it and it had no value to me then so it is filed on a dead computer somewhere. However from memory the book listed most UK tracks and their win statistics for inner middle and outer barriers. In a field of 18 it would list the inner 6 barriers middle 6 and the outer 6. It gave these in lenghts of races and field size and standard track variences. From memory there was a discussion about the effect of barrier bias and the some barrier draws on certain tracks were such a disavantage that if a horse drew that barrier the trainer would scratch the runner. You could clearly at 1600M say at Ayr you did not back barriers 6 to 10, however at 1200M this was less a problem.
Is there a database available for Australian track bias?
