This chart explains a few things. Not of g2 specifically, but of
distortion behaviors of Pentodes. An unbypasses resistor on g2 could
essentially be helping by lower reflected impedance to the plate, so a
little is good, but too much isn't.
An unbypassed screen resistor might lower plate impedance, and lord
knows what else, but it isn't going to do a blessed thing to OPT
impedance.
This could be why small value resistors (relatively) make things sound
better and larger values do not.
