If anyone understood all those graphs could you translate for me please?

There was only one graph, the normal distribution one, and I was not sure what his point was, other than the distribution of probabilities is a normal one. It's been a long time since I did statistics, too. Perhaps one of the other mathematically inclined can vet his reasoning. I mainly concentrated on his explanations of how the mass comparison "method" works.

1. The lack of consistent phonological correspondence between languages (say as between Latin and French or Italian, for example).

2. The phonological and semantic leeway in the mass comparison "method".

His conclusion I took to be that the kinds of mass comparisons that some people find convincing could be no more than coincidence.

Ceci n'est pas un seing.
