[GZG] [OT]Statistics - Correction

Well I have to eat crow, after more detailed analysis there are 16
possibilities with 2 beams vs. 1 with one beam meaning that with 2 beams, the
odds of getting 19 points are only 1 in 1,889,568

The change in analysis results from adding a 6 without a re-roll, which
means it is not fully interchangeable with any other 6 with re-roll, and
since the location of the 6 without a re-roll can change, each change is
different combination and should be counted.
