This simply is wrong. The few who know the approximates also have lots of savant money with which to tsunami the pools.

It has been like that for a painfully long time, and I'm amazed that this should be disputed.

These big players didn't get where they are by being philanthropists and intentionally leaving even a scrap for anyone else.

There's no need to take anyone's word either way. It's easy to satisfy yourself with a test similar to what I recently undertook on the NSW TAB.

11:43 $3,024
11:44 $3,788
11:45 $5,278 = AST + actual jump
11:45+ $6,797

In this piddly NZ jumps race the pool nearly doubled from 60 seconds before actual jump until close.

So nearly half the money in that pool was very well educated. That is an overwhelming proportion which must crush Overs - particularly with a 21% rake.
