That's exactly how I was using it.

I'm not changing it at all. Notice the length parameter is a
constant, 6 in one case and 4 in another:

They don't change from bar to bar. There is no restriction to using
two different lengths in two different calls. You can do the same
with xAverage, for example. And even so, from the numbers given in
the AD column below, there is *no* length parameter that can produce
a slope of -90.12 from the previous AD values. The mm1 column is
incorrect. The mm2 column, from the same function, is correct.
Strange, huh?
