That would mean you could still get the ahead/behind values if you aren't that far behind but would only get "different" if that calculation gets too expensive (which implies the actual value isn't going to be all that helpful anyway).


After a off-line conversation with the others I'm going to look into
a version that is limited to n commits rather than be completely on or
off.  I think if you are for example less than 100 a/b then those numbers
have value; if you are past n, then they have much less value.

I'd rather do it by a fixed limit than by time to ensure that output
is predictable on graph shape and not on system load.
