HotCopper Jan Tipping Competition, page-7

That is a very unfair post if you care to think of the effort these guys all put in to try and win a little $500 bonus.

It takes working all month to do it, whereas most could make it in a day on a real tip if they had the cash to place.

Meanwhile, management are always looking at how and when to change style.
About 300 members a month start at giving this a go, but many drop out when they believe it's no longer achievable to win, and stop putting in the fight, but when it's a close month, you see the battle going on to the last day.
