Just wondering if someone could please give me some results.

I want to know the profit/loss if you were to box triecta's for numbers 3,4,5,6. $12 for .50c in greyhounds.

Actually ignore that previous post. My mate who mentioned it to me had probably had a few by then. Had a quick look at some results and I can't imagine it being profitable. There were a few handy returns though.

The real world doesn't appear to agree with Mathematics sometimes.
Having said that,if you took a large enough sample you would find there would be a loss of 18% or close to it.
But the real world tends to avoid those boxes so a guess would put it at closer to 10% loss.
