And I suspect you use NO diopter at all without the magnifier.
Younger eyes can make the changes needed when going from standard viewfinder to one with a magnifier attached. Older eyes, like mine, can no longer make those changes, IE that is why we older folks wear reading glasses and need a different diopter when using the magnifier.

I tried three, +0.5. +1.0 and +1.5, focussing on items in a display cabinet some 2 metres away and then on a very useful set of iron railings across the road. I took my time over this in order to try to get it right.When I got to the +1.5 it was clear that for me the +1.0 correction was the best.
I confirmed this result this morning. I focus on a small grid of 16 squares just 13mm sq
(blank finely bordered cells, printed on white paper, from MS Excel) from a distance of 1.7 metres. The cells now snap absolutely clearly into focus.
A great result.
