Oh! You are correct. (I had to test it myself, just to see.) You have probably
mentioned this in previous posts, but I did not pay good-enough attention. :-(

The way the documentation is presented in "3.7.2.3 Sampling Parameters &
Methods" has always confused me-- as to which media parameters belong to which
media method. It skips around between method 3, then methods 1 and 2, without a
clear (to me) delineation between the three. I guess I'm just reading it wrong.

Then there is this explanation -- which refers only to Method 1, I guess?

"The samples Min, Max keyword specifies the minimum and maximum number of
samples taken per interval. The default values are samples 1,1. The value for
Max may be omitted, in which case the range Min = Max will be used."

So by omitting the 'Max' value, I admit that even at this late date I really
have no idea what is meant by "...the range Min = Max will be used." What range,
if only a single sample value is specified? What does 'range' refer to?
