I am talking about after the fact, though I am comparing "max grade" readings. I think that maybe since the Garmin records data every few seconds, it captures different parts of the hill on every ride. I am aware of the lag when looking at data on-the-fly.

I'd agree the display isn't very accurate over short distances particularly. However, looking at profiles after the ride, it seems to be pretty accurate for grades of any length.
