after getting all horses which qualify under rule 1 and 2 and 6.
ignore rule 4.
from these qualifiers I eliminated those which don't comply to rule 3
i.e ls odds of 10.00SP or more.
( 47 runs, 2 wins $ 6.00 rtn..... 12 places $ 50.80 return )
of these those that began at 11.00 or more ( 0/29 wins, 7/29 placegetters for $ 40.10

worth noting is that 18 of these began under 11.00 odds ( 2 wins $6 rtn, 5 places for $ 10.70


now those further that began over 11.00 odds , but passed rule 3 were
32 horses ( 0 wins, 3 places $ 12.70 rtn )

thus 47 2 6.00 12 50.8
+ 32 0 0.00 3 12.7

= 79 2 6.00 15 63.5
less 18 2 6.00 5 10.7

equals 61 horses 0 wins 10 places 52.80 rtn
