i totally understand lol ... my babies are still wee babies and they are "pretty good" at using the wee pad (or going RIGHT next to it lol!) on some days and then other days i swear they potty wherever they want!
we use really excited praise and little treats when they potty in the correct place and miss buffey has recently associated going potty with treats and EVERYTIME she potties, regardless of if she went in the right place, she looks up at us right after ready for her treat!

what a little stinker!
but they are so cute, i have only found myself getting annoyed once and it was my fault as i was just tired that day
