I have had no trouble with Q=200 coils. I have a Boonton Q meter that
verifies this when the correct core material (especially in a toroid) is

Bill,
what I meant is that "when you want to make a coil with Q=200 - not
180 or 190" you may have to try some times if you haven't any
experience from which materials gives at least Q=200, a higher Q may
always be reduced to 200 with a resistor
Yes, I have a Radiometer Q-meter - quite old, almost as old as yours,
with thermionic tubes from the 30's and 50's, hi
