I'm sure some of the sharper punters will correct me if I'm wrong Kev, $1.00 = 1 Unit. I think that your on the right path but if you have multiple selections your unit would be worth a lot less. I'm taking a stab in the dark and I think that if you had 4 selections in each leg of the Quaddie for $1.00, Your winning 1st leg would only have 25 cents carrying over to the next leg etc. I think it's best to leave it to Breno, Brent or Ash to confirm or correct this. I'm still a little old school with a lot of the betting exotic's and had a crack at the Quaddie a few weeks ago and after getting the first 2 legs, The Third leg narrowly missed and the 4th leg got up, A fair bit of fun to be had with this type of betting.
