Carbon Fiber Seat Stays = Better Ride?

It is a mystery to me how any frame maker can say a titanim frame,that
lasts forever and having a wonderful ride, can be improved with carbon
plugs or a supported at both ends, carbon rear end glued in.
If I remember well, FIETS magazine did a test on bikes with carbon rearstays
by putting lots of measuring equipment on the bikes. If I remember well
they claimed that a carbon Giant was more comfortable than other bikes
without carbon stays a.o. a Colnago Mexico). A former tech editor wrote a
letter about it saying it was all nonsense. Maybe some other dutch FIETS
reader remembers the results of this test?

It is an unneceassary addition that makes things more expensive, less
reliable.
I ride a few different bikes and I mostly grab a 15 year old SLX bike that
according to all ads is worthless. When I compare it to my carbon LOOK I
can say I feel the LOOK is stiffer, but I doubt the LOOK is more
comfortable. I ride as fast on the heavy 8 speed SLX bike as on carbon
frames. Maybe it would be different in an area with lots of climbs, but not
here.
