OK. I missed that. I saw your comment regarding no length contraction reciprocity.

Now it is my turn to reverse roles. If you assert reciprocity doesn't exist that runs counter to the generally accepted equivelence of frames as advocated by SR.

How do YOU assertain which frame will suffer time dilation or contraction?

The rule is the "A" frame is at rest and "B" is in motion AND "B" is at rest and "A" is in motion.
