Using prediction points for P4, drive digits projects your triads, lets do snap test (10 combined)
draw key drive triads hits draws

Inference>(optional)
6 out of 10 were hits for span 2 to 8 draws (cost ># picks x span) Key set is waged for the span, it helps to do at least 5 test to confirm your keys, especially the drives, see first 5 drives of this test>70,78,81,87,78, this may help in forming the triads, 12 picks is suggested for chosen span, in this test, cost will be 12 picks x 8($96).
