Thanks for that Chome - that is very interesting.

Another point you raised also requires thought. When do you consider a horse firming or drifting? As a $3.00 favourite that went to $3.01 could not be considered to have drifted in price.

I was considering a 2% shift either way for it to be considered either as firming or drifting. It would therefore follow if it was + or - 2% it would be considered as steady in the market.

Firming	Initial	Drifting
$ 1.96	$ 2.00	$ 2.04
$ 2.94	$ 3.00	$ 3.06
$ 3.92	$ 4.00	$ 4.08
$ 4.90	$ 5.00	$ 5.10
$ 5.88	$ 6.00	$ 6.12
$ 6.86	$ 7.00	$ 7.14

Anyone any thoughts? Thanks Fred
