between sea level and 2,000 feetVT altitude. By far the biggest factors are still game day temperature & humidity, much more than very slight differences in gravity of 9.80665 vs. 9.80449 or air density 1.225 vs. 1.112. The ball will curve a bit less at altitude.
Now, go up to like Denver at 5,000 feet, and the differences start making a much bigger impact.
