I tend to sit down to pee most times (at home), so that ratio is even higher for us..

At home both of those are invalid. You close the lid before you flush so you don't spread particles everywhere (among many other benefits)

Everyone opens the lid/seat to the desired level. Everyone does their business. Everyone closes the lid. Everyone flushes and washes their hands.

True gender equality!

autistic women are the best

That's just basic math. +Sit the fuck down when pissing at home. Who is paying you to stand while taking a piss when you could sit down?

I mean, it'll be less than 3/4 if you always stand to pee, because people pee more often than they poop (of they hydrate sufficiently and there's no health issue). But it'll still definitely be over half, so the result is the same.
