+1 Everything can happen.

I remember my a awesome section, starting from 200-300$ and win a lot + reaching my wagering of almost 400,000$ USD. Sometimes is not always about the house edge, but the result of each section bet.

Remember, with that high waggering bet you're not getting prize race but you got weekly & monthly. From my experience can reaching more than 500$+ from the total weekly, monthly and your race prize.
