Each and every user should take a long look at this.
Two users are modifying the hypotheses of a well known and established experiment, the Sagnac, to suit their own purposes.
You are totally incorrect,
Mr Sandokhan, the results that I have been presenting are exactly in agreement with the accepted ideas on the Sagnac delay.
Read again!
Sagnac Effect, E. J. POST, Rev. Mod. Phys. 39, 475 (1967) – Published 1 April 1967 we have
Section III. General Aspects of the Theory, near end p. 478
Summarizing, the experiments of Sagnac, Pogany and Michelson-Gale and the results of Harress, as re-interpreted by Harzer, demonstrate beyond doubt the following features of the Sagnac effect. The observed fringe shift
a) obeys formula (1);
b) does not depend on the shape of the surface A;
c) does not depend on the location of the centre of rotation;
d) does not depend on the presence of a comoving refracting medium in the path of the beam.
Please note that E. J. POST specifically states,
"does not depend on the shape of the surface A;"
"does not depend on the location of the centre of rotation;"
Care to explain in your own words what
"does not depend on the shape of the surface A" and "does not depend on the location of the centre of rotation" mean?
This is more than just trolling, or not debating in good faith: it is called scientific illiteracy.
Just who is trolling? Much of what I present is from papers, many that YOU sourced.
You are the one showing totally scientific illiteracy.
I am debating with 100% good faith,
but you are denying what has been known and proven experimentally right from Sagnac himself on!
rabinoz deserves a long ban for this: after the moderator stipulated clearly that she locked the thread, he opens a new thread and also comments here, using the same scientific illiterate arguments.
Please show just what "scientific illiterate arguments" I have presented.
And while you are at it read:
The Scaling Theory VIII: The Sagnac's Interference and Michelson and Gale Experiment. In that paper, in
14.5. Rotation About an Arbitrary Point, you will find the derivation for the Sagnac delay of an arbitrarily shaped polygon rotating about an arbitrary point and look at the result:

Yes, exactly what JackBlack, I and all the references say.
Do you want me to repeat all the quotes again that say over and over that all say:
In most textbooks result (5) is expressed by the fringe shift in units of the wavelength λ0
∆Z = 4 A · Ω/(c λ0)
where, in general, the scalar product of the oriented area A enclosed by the light path with the vector angular velocity Ω enters. One can show that the fringe shift is independent of the shape of A and of the position of the rotational axis, but depends on the cosine of the angle between A and Ω.
Just face facts, all the references say,
the fringe shift is independent of the shape of A and of the position of the rotational axis.
