KV,
The real money is usually put on too late to follow, but what you have to remember it may NOT be put on the TABS.
Just think of how many betting places there are that pay out on the TAB divi, usually NSW TAB.
So the smokey is set up the sheep follow,the smokey comes in, the nag they want to bet goes out, and the money goes on at the last few seconds.
There was one offshore betting agency that was nearly sent broke by the smarties using this method, until they realised what was happening.
Just remember the smarties are making a fortune out of this game, and it's usually not the main meetings.

Cheers
