I may be wrong, but I think there is a gap between finishing the last line and
starting the next refresh, in which case you would tend to get the same value
a lot of the time.  There is also a delay returning back to the left of the
screen after a line has been sent.  Good idea though, and still useful in some
circumstances even if I'm right.
