Can anyone explain why Cuban Sunday jumped 18 rating points off his listed win on the 1st of September 2012.

First win since Mar 2011 & its a listed race, what were your expectations, Vortech ?

Horse ran off minimum handicap. Carpenter explained handicap would be effectively 3.

From 80 to 98 is quite a large jump!

BTW which ratings are you referring to Vortech? thanks

That's the rating that has the big jump

Its from RAcing Victoria.
What do you mean by thats the one that has the big jump

The rating that jumped 18 rating points, but you've answered. A fan of the horse Vortech, worth following ?

Worth a follow but the value is never there.

I've given up trying to back an early market horse and just prepared to wait until the fields have been decided.

Green Moon is the obvious horse with a big win coming this spring. Probably Cox Plate

Yep, Green Moon has come back well!

Response from Greg Carpenter

You are correct the rating of Cuban Sunday prior to the Heatherlie was 80 and therefore he was eligible to run in much easier company than a Listed race (i.e. Benchmark 78, 0-82 or 0-89)

The limit weight in the Heatherlie was 95, in other words a horse rated 96 would have received 54.5kg, rated 97 55kg and so on

Whatever the rating of a horse on the limit weight was prior to the race they were running off a Handicap mark the equal of 95.
Having won the race Cuban Sunday has been re-rated to 98 which provided a 1.5kg penalty. You will note the 3^rd horse Streets Away carried 54.5 and ran off his correct rating of 96. Having beaten him Cuban Sunday is now rated 2pts (1kg) higher than him.

While Ebony Rock did not win the race he has been rated 7pts higher than he went into the race (82 to 89). As a non-winner we generally provide some concession to horses who run off a higher mark but for actual winners that discretion is less so
