Yes, I need to move around a bit to hit the mark, and generally ensure full coverage. Not sure how much I'm over doing it, but it works for me. Totally feel like I'm slumming any time I'm forced to use a toilet without one, now.

Seriously the best thing ever. Get one.

If the key is centered correctly (a 2 minute job) then you instinctively position yourself when you sit down.
