I'll check the difference. But it seems to me that for this purpose
("which of A and B is more expensive") it doesn't matter since we're
interested in the relative speed of code.

Agreed, and I have lot's of other ideas + plan on testing things as they
occur in my work.

You're absolutely right. I actually started something automatic, but got
stuck, and thought a "by-hand" start was better than nothing. I'll for
sure see if I can make a 100% automatic test.
Thanks for your feedback!
