playing safe.

[pins]

five sets of four.1.-5. 7.-11. 13.-17. 19.-23. 25.-29.  with one column. 3 to 36. one unit on the five sets of four. and three units on the column. cover 34 numbers profit one unit.  you could put a bet on two of the numbers you have left out and still show a profit. if i played this for a hundred spins how would i finish up. any better system for covering a large group of numbers.
