Originally I walked a total of 16,467 steps since the game came out here in the US. I have a total of 813 watts (I used a lot in the dowsing machine).
I get around 5,000 - 6,000 steps a day, and that's only from walking around in my house and playing dancing games like DDR. I don't know how many steps I'll get when I start bringing this to school lol.
Now, I have 144,891 steps with 7,321 watts. I cheated the Pokewalker by doing this: http://www.youtube.com/watch?v=oRjlH22T-u8
The step counter can't go higher than 99,999 steps for today but it still counts your steps in your total. I probably must have gotten 115,000 steps today in a period of 12 hours.
