No Surprise James R., ANS: On this we agree. And the perception of the observers are: A = 7.50 hours for C B = 4.37 hours for C C = 10.00 hours for C And that is reality for the predictions of Relativity. To then extend the clock run time using simulataneity is to avoid the unacceptable results of the basic time dilation formula. I just said Relativity is mathematically consistant but it is also observationally invalid. I know you don't like that but that is just the way it is. Sorry you find it all a waste of time. It rather draws into doubt your sincereity of your signature line.
