Try reducing the picks with the selected sub-group with digit repeat option:
Assume your sub-group is 0,1,2,4, then your frequent pairs 5C2( digit repeat) will be>>
0,0} {0,1} {0,2} {0,3} {0,4} {1,1} {1,2} {1,3} {1,4} {2,2} {2,3} {2,4} {3,3} {3,4} {4,4}
Add remnant of pool (5,6,7,8,9) +4 members of group to the pairs:
005-006-007-008-009-001-002-003-004
015-016-017-018-019-012-013-014
021-023-024-025-026-027-028-029
031-032-034-035-036-037-038-039

440-441-442-443-445-446-447-448-449
Total picks should be less than 150, this is further reduced by Combo BET, eg you have picks 032,023,013,031 etc. Now assuming your waging outlet permits 25cents per pick, then a combo is just $1.50 x reduced pick will be less than $100 a draw. Note that combo for 3- way (eg 113) is 25 cents x3 .

Lets the sub-group pairs be the test> 0,0} {0,1} {0,2} {0,3} {0,4} {1,1} {1,2} {1,3} {1,4} {2,2} {2,3} {2,4} {3,3} {3,4} {4,4}
You had 26 wins out of 40 draws, now try to finish generating the picks, cancel similar picks (since you wage combo bet) and see the remnant picks. You can also select the most frequent pair considering the option 5C2(no digit repeat) for 10 distinct pairs, add remnant of the pool+ four members of the sub-group, delete similar picks for picks to be wage. Good luck.
