Then yesterday, Hobart 6/8 Our Artie, definitely ran - I've seen the replay, but given as a scratching on TasRacing's web-site, and on WATAB, albeit with tote prices displayed, but not on TAB's site which displays Fixed and tote prices.

Weighed in light? Have to wait for the Steward's report for that one. Or Mike McBain.

Then there are the SP markets, which in about 0.6% of times are <100% because of barrier scratchings, and in many other cases low 100s, not reflecting the real SP after deductions, but are still used by touts to promote their systems. 

I calculate a normalised 100% market for every race, not by the simple method of dividing each price by the market%*100, but taking into account the "long shot effect" and use that as the basis for comparing returns.

Using on-line bookmakers prices is also fraught.

Here's the final prices as per Dynamic Odds from a number of bookmakers on Race 7 at the Sunshine Coast 27/9/2020:

The discrepancy between the BBet and the others is obvious from the first 2 favourites, #2 and #6:

However, the SPs are right, so the SOPs have been determined considering actual final prices from the (10?) designated bookmakers and the formula used to determine SOP.

Why is BBet the only one right? I can't know, but there were 21 races that day so impacted, the others were ok.

And so on; Life was not meant to be easy, and is not easy for punters.

Len, go to hong kong.

the top weight gets scratched.

the emergency no 13, gets a run; and in HK it's TAB number now has changed to no 1.

when the emergency wins, and as it is now no. 1.

my data provider credits the scratched horse as the winner !

cleaning data the bane of my life. 

cheers sean

An example of how hard it is to keep data bases accurate:

The results for Yeppoon Race 5, October 1 on Racing Queensland's web-site show:

2 Presley Road

T: Damien Rideout

J: Matthew McGillivray

6 Blame It On Paris

T: Zoe Hohn

J: Emma Bell

While the Stewards' report shows:

Summary of rider changes/Late notifications

Race 5.  PRESLEY ROAD – M McGillivray

              BLAME IT ON PARIS – Z White

This is far from a rare occurrence! I don't even bother trying to keep trainers accurate - they have Gai running horses at:

Adelaide River,

Atherton,

Barraba,

Bluff,

Bundarra,

Buchan

And that's just the A and B's. Maybe she did, I can't know, but I don't trust the data I have.
