 You are correct, I misspoke. While that point may have
been wrong I did check the elevation of Mount Sunapee
and it is indeed at 2726 feet as measured by USGS and
others. When I posted before I 'assumed' the researchers
were from MIT or one of the Boston area schools (or UNH)
and would therefore be at sea level. Rewatching the video
they do say that the second clock is at sea level but
they don't mention where they are. The drive up to the
base of the mountain would probably be 1 to 1.5 hours
so the 1st clock didn't go from sea level to 2726 feet
instantaneously so during that travel time it was probably
at an average of about 500' which is near the average
elevation in New Hampshire.

If the experiment had been conducted in the  Burj Khalifa
in Dubai, United Arab Emirates and the elevator could go
from sea level to about 2000 feet, which may be the top
floor, the experiment might be more exact because you'd
eliminate the travel time.
