Wesmip1,

At one point I spent about 8yrs specializing in time [got some great long-shot winners too]. The horse racing mag [can't name it here but I'm sure you know the one] had a whole page of all the different aust. tracks and their time variations for distance. I'm sure if you contacted them they would be able to sell you a back issue.

Using time is a very hard way to go. A hell of a lot of work involved and like any method it has it's brickbats. Track condt. on the day, wind direction and strength, the general contd. of the track at different times of the year and even the length of the grass all affect times and then you have to adjust individual horses weight carried at various distances etc. and depending on the size of the horse [hard one to know], different weight +/- will effect their times more so or less so depending on the distance.
I had a formula method I'd worked out I could apply to each horse in any race but blowed if I can find it or remember it, as it was about 18yrs. ago I last used it.

The whole business of track times regardless of how you fine tune it, is always going to be a bit 'hows-your -father'. Still, it definitely has some great pluses going for it as a method of handicapping. It served me OK [until I tired of the work involved], especially over sprint distances. Beyond 1400m it's more about race pace and good sectionals than overall times.

Hope this helps.
