Wait 4 or 5 or 6 then bet that dozen is as old as the hills.
First thing I looked at when I didn't have a clue.
Actually...it makes more sense to bet the hot DD after it hit the 6th time.
Only slightly more sense though.
Or bet the sleeping dozen when it shows up
Remember Murphy's law
That will not give you winning odds better then 99%
Probability and gap methodology is as good as it gets.
