If the boat is not reaching speed it's a mechanical or electrical issue not a wind or current issue.

(that's of course assuming you aren't going straight up a raging river that is pushing back at you so hard that the boat doesn't have the power to overcome it and get to gps speed)

I suppose if you went from an area of no current or no wind and then into an area with current or wind your speed would fluctuate a bit until the zero-off catches up to the change, but that's not what repomannv was talking about I don't think. He's talking about setting the cruise at 14 and the boat goes 11, that's a mechanical or electrical issue and not a wind or current issue (again unless we're talking about extreme currents like tides)
I can't explain it in terms you are going to understand I guess, but speed over water is different than speed over land. That is why the different makes have or had up river or down river offset settings for gps zero off... I will google research later something that shows better than what I can articulate.
