Totally Irrelevant, it is Out The Gate punting an unrestricted amount of money at full odds with no slashing of odds, for a group, not individuals!
if it is 300 people punting at the same time then the odds would be slashed accordingly.
It is about the liability to the TAB for each bet and it is just a continuation of how the TAB treats some very loyal punters poorly, whereas others get favouritism!
This policy of treating punters differently has gone on for a long time but does not make it right, and if you knew the full story then you would understand more!
