And you're ignoring self-selection and rhetorical exaggeration.

I'm sure the women the guidance counselors are speaking to are the ones who need the most guidance, and I'm sure the counselors have seen a jump in student e-thottery, a jump large enough to make his mother say "nearly every girl."

You need to let go of the rhetorical incidentals and get to what the mother was actually saying: "We've seen a jump in student e-thottery that has us alarmed."

See? Quit applying linear math to a network visibility problem.
