(Anyone interested in the wheel that Dennis used, check out his posting under Lottery Wheels -- from main page)
That was good that you went with 38 as a DN (due number for those
). Did you simply play the 16 like any other number on your wheel.
If my calculations are right, DN+9 requires 126 lines for a full wheel (9!/(5!(9-5)!)), which you create 30 lines from. Using DN1 and DN2 with 9 numbers (total 11) would require 126 lines (50% more than 84 lines for 9-wheel).
So playing 16 and 38 with 8 numbers would require up to 70 lines (8!/(4!(8-4)!)), compared to a regular 8-number wheel (28 lines). But then you really count on those two numbers showing up.
Playing 16 and 38 with 9 numbers would also require up to 126 lines (9!/(4!(9-4)!)).
Have you ever tried creating the 126 lines and filtering them down (2+ even, sum range, etc) to see how many you can work with instead of the 30 lines ?
