I concur. The angular motion is what makes faint meteors noticeable.
One test would be to compare the mean magnitudes of both samples and
see if they're statistically significant. My recollection is that most
`point meteors' were +1 or brighter.
I think the perception of short and point meteors varies considerably
from observer to observer. This is based on my experiences in group

The regulation distance was 40 away in my days a visual observer. The
reason why I see higher-than-average number of faint meteors is my
fortunate ability to detect faint moving objects across a wide field
of view. It's so amazing that I often detect satellites just before
they enter the field of view of my telescope. It's spooky. My guess
is that's it's some reflection in the Koenig eyepiece stopped down to
a 1.25 inch. Now only if I could do that for meteors.

That sounds eminently plausible to me.
