Predictive model for US Powerball #'s

For the record, for the 7/4 drawing:
PB grouping correct? - Yes
For the main #'s - One of five correct
It's nice when the PB grouping hits, won $8 on $10 ticket. I only play one ticket per drawing.

For the 7/7 drawing:
For the PB, PM like one from grouping (11,18), Alt grouping of (4,7,8,13,15,22)
For the Main #'s, PM likes:
One from grouping (12,14,22,38,50,51,55)
One from grouping (1,24,25,32,33,37,62)
Two from grouping (3,18,21,26,43,53,54)
One from grouping (17,23,61)

Best of luck!
