Racehorse TALK

I have posted this discussion on the Racing Talk Australia banner although it relates to Tabcorp's declaration on Supertab on race one this evening on Singapore race one won by Rocket Man as I believe the thread would get lost posting under International Racing banner.

Supertab co-mingles its pools with the Singapore tote, however on its website Tabcorp has the following rider...
Key points where the Singapore betting rules differ from the SuperTAB betting rules are as follows:

    * Dividends are rounded down to the nearest 20c.
    * For the Win pool:
          o Minimum dividend is $1.20
          o Minimum starters is 4 

Prior to the running of the race the Supertab not only displayed the approximate win dividend of $1.20 for Rocket Man but showed the pool was co-mingled.Rocket Man paid $1.20 on the Singapore, the guaranteed win dividend, however Supertab declared a win dividend of $1.04. I rang customer service to seek an explanation why the dividend on Supertab was not declared as $1.20 but was told that the Singapore tote, for "technical reasons", had withdrawn the Supertab investments from their co-mingled pool.I was then told all other up-coming races will be co-mingled.

Praiseworthy, I would be pleased to know why Singapore would want to exclude Supertab investments on this particular race where Tabcorp are winners at the expense of punters who backed the winner ?
