For some reason Unitab divvies are generally lower than the other Tabs right across the board.We don't have flexi bet,but you can take multiple F4's for a 25cent unit.I think Chrome hit the nail on the head,when it appears to be a race with only 2 main chances the big punters stand them out to run 1-2 with 4 or 5 others to run 3rd @ 50 or 100 units,then add in all the flexi bettors that stand them out with the field(as Crash does)then the high % takeout,and your value goes out the window,even if a 50/1 shot runs 3rd!
