Are your eyepieces optimal shortest focal length always the same as your scopes focal ratio

Thanks John, that was what I wanted to know. Not just me then.

Jupiter rarely seems to benefit from high magnifications.

I would add "at a given aperture under good seeing conditions".  For example, years ago at a star party, on the same night that Jupiter looked featureless at 200x in 4" APOs and 8" SCTs, it looked rich in details in a 15" custom Dob at over 300x.  That convinced me to buy a used 15" Tectron Dob.  It did not disappoint.  300x felt like 100x in a small scope.  Of course, I had very steady skies to observe from here in Texas.

Good for you, nice scope
