The owner manual suggests
keeep the oil level between the limits.
Surely the best approximation to that
is the middle.

I could be wrong
about the crankcase pressure,
if two pistons are going up
and two are going down
at the same time
it shouldn''t make a difference.

Anyway, can't do much harm
I've done that for the last 40 years
without problems.

Or am I a tad obsessive?

Now that I think of it
isn't it just as obsessive to put it at the full mark?
