Rather than storing a bunch of predictably increasing numbers in arrays, why not just do a little math inside your loop? For example, the code you posted theoretically creates 10 frames. Here's a cleaner way to do the same thing:

local frames = {}
for i = 1, 10 do
   local f = CreateFrame("Frame", "LLCheckButton"..i, newRaidWin, "UICheckButtonTemplate")
   f:SetPoint("TOPLEFT", newRaidWin, 180 + (i > 1 and (80 * floor(i / 2)) or 0), -30 - (20 * (i-1))
   f:SetSize(22, 22)
   f:Hide()
   frames[i] = f
end

Math may be faulty (I didn't test it at all) but the theory is sound, and a lot more flexible than storing fixed arrays of coordinates.
