Just re-reading your post I thought I would add the following thoughts.
If 25 watts from a particular antenna is
full quieting and 15 watts from the same antenna
sequentially measured...is noop... this is not a

No, you just got confirmation that you had the duplexers close to spec, and the
cost is not out of line for labor and test equipment if everything was done
correctly. You only tuned one piece of the entire system however so there may
be other things lurking in the background.

repeaters I used nothing more than a signal generator with attenuator and an ht
with a bar graph signal strength meter. That and a dummy load is the minimum
you really need to do a decent job. I replaced a 2 meter
