I saw the equation before but not in context with logistic mapping. It was applied more to population increase/decrease.

So.......

If we were to substitute the first digit of any 5/39 lottery drawing for X and did some iterations, would the next drawing's first digit be found within, say, the first five iteration?

I will have to program this into the computer and see just how many iterations must be performed before there was a match between the two drawings.
