Thanks joesph_h.
That looks like a considerable and a really statistically significant decline. I think if the "curve" continues, into 2010, the numbers looks to be a 1/2 of what it was in 1998, which was the year before mandatory operator training became effective, if I remember correctly.

I think all operators, and the trainers deserve a piece of "safety cake" for this result.
Maybe the effort really is worth while after all.
