But you set FOV of 1.86° (no digital zoom) and got about the same fit as I did in the first attempt above (#62). I have reproduced your fit, the trail is still about twice higher than the track.
Perhaps it was a secret sprayer deployed to thwart you record attempt by flying parallel to UAE205 and closer to your location
Or there was an atmospheric refraction lifting up the trail appearance by a small fraction of one degree…
It should be higher than the track. Something like 0 .1 degrees for the conversion from barometric altitude to geometric, and something like 0.25 degrees for refraction (like sun).
