Hey David, a unit is symbolized as a dollar amount you play from 1-10 or whatever, just say 1 unit is= to $100 so when you post the unit, its pretty much to win on a fav or lay on a dog, at least for me it is.
So for me for example 1*=$100 and I play Sharapova at -150, I would lay $150 to win the 1 unit=100$ and for a dog say Sharapova +150, I would lay 1*=$100 to win 150$ so if I layed 1*=$100 and won I would win 1.5*=$150 on the dog.
Say for instance you play Guga -130 for 2* and your 1* unit= $100, then you would lay $260 to win $200 so the units would be simply 2.60*Units to win 2.00
Say for instance you play Guga at +130 for 2* and your 1*unit=$100, then you would lay $200 to win $260, units wouls be 2.00* to win 2.60*
I have my units like this (a fav is to win) and (a dog is to lay)
Hope this helps
