Keeping the draw level at 30 draws. The pairs shift as the 2 oldest draws are kicked out and the 2 current draws kick in. That would be obvious.
Kicked out 856-587
Kicked in 431-131
That shifts the pairs that are in those numbers.

Have been lucky the last couple days as the 2 matching pairs to make a number have come in the same tier. 3 pairs in a no match as I said before but only takes two pairs to make a combo no match or double. You will not find trips in this system.

I think I got all the combos possible in each tier. Do it by pen and paper .

all ascending order.
