Your theory is falsified.
I tried, in vain, to explain to Richard how his claim : “If the paths
are equal, and the observable times equal, then the proper times will be
equal” is asinine :

1. Given two distincts trajectories, "equal paths" is a frame dependent
property it CANNOT implies something which is NOT frame-dependant
(equality of proper times)
2. "observable times equal" expresses nothing more than the equality of
difference of time between two events with... itself

Out of Galilean Relativity, where proper times are always equal (and
then the whole claim is void), this is logically impossible.
[snip whining]
Not at all, this is obvious to any sane person.>Absolutely not.
And also I pointed out with full details how his claims implies, as
you wrote, that this leads to equal times for any twin scenario.
You lie.
