I've also lowered my usual 100-yard sighting in most cases to make precise placement at practical ranges easier. Long shots aren't common here, but quick ones are. It's hard to remember to hold a bit low when you're rushed; easy and natural to hold up a bit at longer range.
Me too, I seldom setup more than 1.5" high at 100. Normally I sight in at 200 because I tend to hold higher at distance than needed.
