The 1,2,3,etc. is your 1st.2nd.3rd Selection in average prize money order .

As stated they dont have to run in order ,it can be any order, as long as the 2 anchor bets dont get up together(I`m talking about the $72 version.)

These are called Rovers, because they must fill one of the three placings,otherwise we miss out.
We dont want both rovers getting up in the same race together.

You will find ,that if you take the 2 shortest priced horses as per
pre-post prices as per newspaper, that they very rearly appear together in the placings & when they do, they don`t pay much, therefore not worth spending good money to cover ,when the return is ordiary.

By the way, some people may feel that the derrogitory race comment,(which I won`t repeat)
politicly un-cool. Sorry ,butI just feel you have know.
