Does pulse tuning at max PEP out with a higher plate voltage than normal
really give you more over head, or less.? IOW, you are tuning up at a
higher plate voltage than normal as it won't have the normal sage
related to normal use on SSB let alone CW. Or is the difference not
worth worrying about?
I normally tune into a dummy load while adjusting the antenna tuner with
the antenna analyzer, then switching to the antenna which was adjusted
to the same figures as the dummy load.

Unless running near the amps limits I'd not expect this to represent a
