BTW: what does limit the performance of the super-5065?
(short term, ie <100s)

Apparently, from the description of modifications I've seen,
the standard-5065 is mostly limited by detection noise, either
due to noise in the light, or the RF chain.

Could it be that the super-5065 and the A1 modifications have
shifted the limit to the detector/correlator and integrator?
Or does the Dick effect already limit you?
