In our universe: The clock that accumulated less clock seconds between
meetings cannot claim that the clock that accumlated more clock
seconds as running slow.
It doesn't (for average ticking rate for the trip).  You don't know what SR
says.
But that's what SR says.....a clock that accumulated less clock
seconds between meetings can claim that the clock that the clock
accumulated more clock seconds as running slow.

A slower running clock cannot claim the faster running clock as

EverySRobserver uses the same equation to determine the rate of an
observed clock.
Yes they do .. but its not the equation you show if either the observer or
observed is not moving inertially.  
No object in the universe is moving inertially.
Your problem is that you only have a
coffee-table 'understanding' ofSRand think from that you know all that it
says.  You don't.

kenseto says...
They can change velocity and becomes inertial again. So are you saying
thatSRis not valid after an observer experienced acceleration?
He isn't saying that.  Nor does he say that he is.
The usual equations ofSRare only valid if used in an inertial
coordinate
system. If you apply them to a noninertial observer, then you are not
doingSR.
So are you saying that after acceleration an observer will forever
becomes non-inertial?
He isn't saying that.  Nor does he say that he is.
You really do learn to read.
When the observer and clocks are both moving inertially, then the particular
special-caseSRequations for time dilation etc that you are quoting apply.
Those equations do NOT apply during the period of non-inertial motion.  SR
can still handle that case, but NOT with the equations you cite.
We are talking about the objects after acceleration.
The equations for clock ticking rates for inertially moving clocks apply
only to inertially moving clocks.  They are not the same equations as for
non-inertially moving clocks.
Really ... its not hard to understand that.
