As I pointed out to Jimmie Robinson privately there is in fact
one assumption being made here: The assumption that Newhouse did
indeed hold the camera steady and allow the objects to pass
through the FOV.

This was the very assumption that the Robertson Panel called in
question, suggesting that someone trying hard not to pan with
the action might have unconsciously oversompensated and panned
_against_ the action, thus inflating the apparent angular rate.
Newhouse's assertion that he did not do this may (or may not) be
a good one, but it does not unfortunately have the status of
"scientific fact" in the sense claimed, so it isn't "as simple
as that". It may be possible to calculate some plausible limit
on the amount of angular error that could arise from such
overcompensation, but I haven't seen this argument explicitly
tackled anywhere. Has anyone else?

That aside, its's very interesting story from Mr Robinson,
though.
