> is this an issue?  we simple have no information of sperm viabilty as it relates to good queens.

Not true at all. Jeff Pettis published this one a few years back, and it's been mentioned many times.

Low sperm viability was indicative of, or linked to, colony performance. To explore the source of low sperm viability, six commercial queen breeders were surveyed and wide variation in viability (range 60–90%) was documented between breeders. 

Pettis, Jeffery S., et al. "Colony failure linked to low sperm viability in honey bee (Apis mellifera) queens and an exploration of potential causative factors." PloS one 11.2 (2016): e0147220.
