Just been reading your adventures with 3 Cs clocks, a mountain and 3 kids,
but I can't make the estimate of time dilation work out.
You measured ~ 23ns and say it agrees with calculation
The equation quoted in a related reference, for "low elevations" is g.h/c²
which if you plug in g = 9.81 m/s² and h = 4300m for Mt Rainer gives an
expected value of 4.7 * 10^-16.
Over 2 days, 2 * 86400s, that would be 81 ns in total, four times your value
What am I missing?
Was just speculating what Ben Nevis at a mere 1340m height might offer
Considering the parking lot is around 200m, carrying the clocks and
power to the top might be moving from a moderate walk to the strenuous
category. One might also want to do this in summertime, so you've got a
few months to plan the expedition.
I wonder what the highest road in the UK is?
