If one chose to play a small wheel with their own numbers it would only apply to the top prize, plus to the 3/4 ($50) and 2/4 ($2) in one (1) set, because the rest are QP's.
But, say one picked 16 numbers from 77 (roughly equivalent to picking 10 from 49 in a 6/49 lotto) to play a small wheel, then:
CM(16,4,2,2)=23 <-- cost $46 for a 2if2 guarantee, win $2 min.
CM(16,4,2,3)=12 <-- cost $24 for a 2if3 guarantee, win $2 min.
CM(16,4,2,4)=09 <-- cost $32 for a 2if4 guarantee, win $2 min.
CM(16,4,3,4)=73 <- cost $146 for a 3if4 guarantee, win $50 min.
I'm new to this 4/77 game but at first glance it ain't so hot despite the seemingly favourable odds. Note the wheels were quick and dirty, made with CoverMaster, someone may have better ones ... so the actual mileage may vary

. The idea to pick 16 numbers was just for illustration. Using less numbers will bring the cost of wheeling down, obviously.
