Betfair have a page where you can get the best dividend of all 3 totes plus top fluctuation or something.
Lets not worry about the fluc thing , and lest just say it was the best of the 3 totes.
They also have a middle tote where the dividend is the 2nd best of the 3 tote dividends.

Now I'm obviously missing something.
Could someone explain , or send me to a web page , and why would I take the middle tote wager , when I can get the best tote wager?
