I have been using 20.94 percent and it looks like 20.9 is the accepted
number.  The oxygen content in the dyno room is measureably lower
than outside air (Bosch LSU sensor).  Does anyone know if this will
have any effect on the sensor accuracy?

Free air is 20.2% O2. Just like you learned in Chem class. The sensor will
read it like this, too !
