Hi Okiebowie,
The issue of arrows hitting higher at higher elevations above sea level is almost always due to the fact that as one gets further above sea level air becomes thinner, thus increasing the ambient pressure within an arrows shaft. This increase in pressure causes an arrow to fly flatter for a much longer distance before it begins to drop.
I've watched archers out in the western U.S., in the Rocky Mountain States easily taking shots at large Jack Rabbits at 90 and 100 yards. because their arrows would carry flat so much farther than they would at lower elevations.
It's somewhat similar to the extra arrow elevation that we get during the hot summer months, but even more so. Heat will also account for additional pressure build up within an arrow shaft, so this causes a raise in impact points from when the crossbow or compound bow was initially sighted in at sea level or during cooler temperatures.
