Did you measure the distance AB using a measuring tape? Or did you use the
time difference (t'A-tA) and the standard definition for a meter
(1/299,792,458 light-second) to measure length?

First of all, perhaps you don't realize that this standard for the
meter was adopted in 1983. People measured c before 1983.
There was a published value of c good to at least 8 or 9
significant figures. Where do you think that came from if nobody
ever measured it?

When this was measured prior to the 1983 redefinition of the
meter, it was done against an independent length standard.

Second, when you are measuring a velocity of something,
you measure the time and distance separately. Only an idiot
would think you use the same time measurement to calculate
the distance. Even now if you did a speed of light measurement,
you wouldn't do it that way.

Third, when I was a physics lab instructor, it was prior to 1983.

Did you measure TWLS at
different distances of separation between the source and the mirror? If you
did can you give us the results or can you give us any published results?

This was a freshman physics lab. The results of homework
assignments are not typically published or even kept in anybody's
archives for online perusal 25 years later.

Also, unless it extended the limits of precision, i.e. added knowledge
to the scientific community, why would such a measurement be
publishable?
