Roy,

Well the intuition was correct, however the problem is one level more
complex. The Smith chart shows the following approximate 'mirror'
relationships for j=0:

Load Input Measurement
20 125
25 100
35 71
10 250
50 50

It is a "log" mirror centered on 50 Ohms. The mirror relationship holds
for j /= 0, however the calculation is more complex. - Dan

Well, yes, you can find specific relationships for various special cases
of load impedance and line length, particularly if you assume zero loss.
But only the appropriate equations, derived from basic principles, will
give you the correct relationship in the general case. Be wary of
oversimplification.
