This may or may not be helpful, but I recently upgraded to WiiFit Plus and it has not been as assy about people who have not used it recently as WiiFit was; it actually said it heard they'd been looking stronger and did not press me for any details. I'm not sure if this is because I haven't played it enough to hit that yet or it's an actual change, but if you don't have Plus, I'd recommend it anyway. It's improved a lot, IMO.
