Mine is consistant with using her potty pads for poop,when downstairs,only time she misses is if she has a cling on that drops after she has left her potty pad (sorry for being so graphic) but I am beginning to notice that the times she misses the pad for potty is if there is any poop on the potty pad....guess she is just extremely particular and won't go on the same spot as her poop....She too has also used my shower upstairs on a few occasions during the night when she is upstairs with me even though she also has her potty pad upstairs too...Personally I would much rather have an accident of poo on the carpet the potty that can sink down to the padding...
