Concerning point (C):

I've found pooping with your feet on your tippy toes like a ballerina also does the trick (while still sitting down of course) to achieve the elevation of your legs to be in more of a squat position when pooping.

If you ever go to China and have to squat to poop, that's also a good catalyst to finding the right squat position to best suit you.

Although that's certainly better than nothing, it's really not the full deal at all. Even the squatty-potty which is way beyond just tip-toes is only about half-squatting. I've compared and the full squat is the real deal.

People who want to do it (even in prep for a China trip) better work on simply spending time squatting in general. Apparently, westerners with sit-toilets actually lose the flexibility to do a relaxed, flat-footed squat at all.
