There's two parts to it, steps and watts.Just wondering the pokewalker does indeed save your steps over the long run right? Like say for instance I get 9500 steps, the pokewalker will save it right? Im just wondering bc Im hoping to get that amount before the yellow forest comes out so i can get a surfing or flying pikachu and dont want to do those steps all over if they just reset.
Watts... use 3 to gamble for items, 10 to search for a wild pokemon. Watts, however, are removed from your pokewalker when you hit return from stroll (which you have to do to change courses), because watts stored on the DS go towards unlocking stages.
EDIT - Steps are reset daily.
