Thanks for that. It made me realise that the worst case source impedance
from a 100K pot is not 50K but 25K so things are only half as bad as I
thought. LOL

** Only true is the source feeding the 100k ohm pot has near zero
impedance.

Which is obviously not the case.

Compared to 100K, the 800 ohm source resistance of the mu follower is as
near zero as makes no odds.

Or one would use a lower value pot.
