It's not a investment play, but any thing I say large is over 5* when I post large .med would be 5*, small 3 or less and those are not units 3=.5 4=1 unit 5 is 1.5 the rare 10* 7-9 a year mostly bowl games is 3 units that is all i have really just 2,4,and 5 10 is few and far between just appen to ave 2 on fri and sat cinn and pitt which was a first in 11 years, Also units are different for each person one person might be 50 bucks a unit and for others could be 500 to 5000 a unit.All on the person their bankroll, money management and what they are willing or can afford to lose.
My reg plays on here are for a unit unless i happen to say amount for me,not really my business what someone plays them for on here if they even play them at all.
