Yes, I agree. I'm just assuming that they shouldn't be sequential for some reason. Like here in Austria, according to the privacy laws, certain numbers can't be sequential, because if you see somebody elses number you could guess when he did what, and so forth...

But anyway: That's why I do little work here, I guess. And I agree with your statement.
