Ive been using the WA tab PP prices for about 5 yrs. daily as a price guide because the Melboune Age I have delivered only covers the local country meeting during the week.

The eventual SP price can be all over the shop and also very accurate [less 10 to 20% for SP is about the norm.], which is par for the course for most PP odds anywhere. $2.50 or less runners often start odds-on or close to evens and mostly don't drift.

I mainly punt on horses that are from 2nd. to 5th. favorite SP. Often these runners start favorite, even the 4th and 5th PP favorites [which annoys the hell out of me if I'm backing one of them !]. I've also had some of these runners blow out to longshot odds. One of them to $28 [it won too].

Until recently I had a data-base of all the PP odds for all the meetings covering about three years PP odds. Tragically, they are now lost to a puter crash.

I know, I know ....back-up, back-up !
