You won't have an advantage until you see a +5 count, and you'd need to spread around 1-16 to glean a very small edge. Given the frequency of counts at +5 or more and the implications of jumping from 1 to 16 units all at once, I don't think it's worth your time. At any rate, why fill another seat at these lousy games? It just encourages the casinos to keep them.
