Jack,
Can't agree with your count .. nor the loss you infer.
First .. there are only TWO additional connections .. yes .. there are 
three connectors .. two PL-259 and the 'barrel' .. but they make TWO 
connnections more than direct coax.
I'm not the one who did the test .. it was someone else .. about a year 
or two ago .. and they used good test equipment .. I just stated, from 
memory, what has previously been posted .. and, I believe, that .5 db 
loss is HIGHER than what was posted by the experimenter.
