And how did your control group do?

What language was Perl compared to using this methodology?

Did the test subjects have experience with Perl? And, what of the control group?

Perl is different, no doubt about it. But, it doesn't *have* to look like line noise.

Have you explored PDL (piddle)? I find it to be a very powerful way to manipulated datasets.
