With the running of the Doomben Cup tomorrow punters who rarely punt on anything north of the NSW border are likely to be putting in some heavy hours of home work tonight to sort the form out. We've spoken often enough in our news articles about the challenges associated with doing the form at tracks where punters have little knowledge.

With Doomben's tight turns it's typically harder for the outside runners to get home creating an inherent bias towards front runners. This typically draws attention to gate speed and barrier draws. So just how much emphasis should punters put on the barrier draw? How does that vary for middle distance races like the Doomben Cup? How important are speed maps for a racecourse like this?

For those punters who don't care much for taking a crash course in the peculiarities of Doomben racecourse we've singled out the two highest all time earness tipsters at the track using the entire tipping history at theGreatTipOff.com.

Pro horse racing tipster Explicit boasts 59% win profit from 46 life time tips at Doomben delivering $100 punters a win profit of $2,714.

Next best is West Australian tipster Sandgroper whose Doomben horse racing tips have bagged his followers $2,691 from $100 bets.

This week's Top 10 reveals a serial roughy horse racing tipster who is making a habit out of finding super long shots.

Most of us would be chuffed with a $20 winner every now and then. On Saturday Pie2251 tipped BerryBear at Rockhamptom which paid $66.30. That earned him the Top Roughy Tipster of the week honours. Now if you think that was just a fluke then think again. Pie2251 tipped Daneclicked at Ascot on 27 February this year which won and paid $58.50 and on January 25 he tipped Harlem Shuffle at Canterbury and it paid $59.10. That's 3 winners paying over $58 in the space of 4 months.

West Australian punter Sandgroper makes it 2 appearances in a row in the Top 10 with his winning tip on Saturday paying $29.40. Owzat, ThatWinningFeeling and Pushkin all make appearances in the Top 10 having been here a few times before.

No media tipsters made the Top 10 this time round.
