Just too add my own bad luck anecdote.
NRL GF day 2013. Betting away as usual and had a few programming errors so I set about fixing them between my selections.
My selections are finalised in the morning and are only changed by scratchings.

Meanwhile up in Hong Kong the meeting was going to commence at about 4PM and final scratchings came through some time in the afternoon.

But i am beavering away on my own problems and didn't get around to doing an update from about 3PM onwards.

Anyhow about 6.30 i did an update of results and scratchings one only to see that after scratchings i have missed one at in HK at 6PM that paid $90 that i was supposed to have $450 on.

Still haven't got over it.
