OOOOH it must be so that even if you use watts, your total collected still counts towards unlocking!
So say you gain 10 watts, then use them on pokeradar, it still counts towards unlocking the next course!
Yeah, I just did too. If only it did work that way. :/No,I'm pretty sure if you spend watts in the pokewalker,then they won't still be there when you transfer.I tested it out a few times.
