HOW TO BACKTEST BLACKAPPLE PICK-4 ROOTSUMS
-----------------------------------------------------------------
a) Get your P4 results and compute the root for each one
12/05/2005 Midday 6 1 0 8 rt=6
12/04/2005 Midday 1 0 2 8 rt=2
12/03/2005 Midday 5 6 0 9 rt=2
12/02/2005 Midday 1 3 5 5 rt=5
12/01/2005 Midday 8 6 3 1 rt=9
11/30/2005 Midday 2 3 8 5 rt=9
11/29/2005 Midday 8 9 6 6 rt=2
b) Choose a taget draw
12/05/2005 Midday 6 1 0 8 rt=6
c) Take the 5 previous draws and remove the 4th digit
12/04/2005 Midday 1 0 2 X
12/03/2005 Midday 5 6 0 X
12/02/2005 Midday 1 3 5 X
12/01/2005 Midday 8 6 3 X
11/30/2005 Midday 2 3 8 X
d) Find the missing digits in the previous draws above (c)
4,7,9 are the missing digits
e) If the root is one of the missing digits you may have a hit
missing 4,7,9
12/05/2005 Midday 6 1 0 8 rt=6
In this case there is no match
f) Choose the next target draw
12/04/2005 Midday 1 0 2 8 rt=2
g) Take the 5 previous draws and remove the 4th digit
12/03/2005 Midday 5 6 0 X
12/02/2005 Midday 1 3 5 X
12/01/2005 Midday 8 6 3 X
11/30/2005 Midday 2 3 8 X
11/29/2005 Midday 8 9 6 X
h) Find the missing digits
4,7 are the missing digits
i) If the root is one of the missing digits you may have a hit
4,7 are the missing digits
12/04/2005 Midday 1 0 2 8 rt=2
In this case there is no match
Continue down your list following the same procedure.
