We've been running a test for a few weeks tracking the efficiency of the power distribution center. In the current configuration, it is possible to get the efficiency of the fiber collimator + fibers to high 80 percents. It should be noted as well that there were large temperature changes in the first three days of this data.
The MISC path is a standard 2 axis tip tilt mount compared to the other 3 paths which are the 5 degrees of freedom mounts. The initial theory was there is a relaxation time to some of these mounts on a several day time scale leading to loss of power in the 5 DOF mount. But this suggests something drifting upstream to me.
