I don't mean over time, I mean immediately when you pick a string - it pulls the string sharp. If you don't believe me, pick up your guitar and chug on an open low string while increasing the intensity of your pick attack while looking at a tuner. This is like the most common issue in the world; there's a lot of documentation on this forum of Andy, Lewis, Lasse, etc saying that they tune the low string a few cents sharp to counteract that. Gotta tune to the pick attack, not the open note.
