I've said in both my review and my original impressions that I wished Wii Fit's weight charts had statistical smoothing, but not everyone really understands what that means. Here's an illustration.
I've been logging my weight simultaneously with Eat Watch, putting Wii Fit's poundage into my Palm after my daily weigh-ins, and this is the chart that results (minus the numbers—sorry, that's not my game):
While there's a bit of a lag in the "trend" line, you can see that it's useful for helping to see the long-term view, illustrating one's trend rather than the mountainous ups-and-downs of day to day water retention, digestion changes, and stress. Considering that any exercise program is going to work best over a long period of time, the trend line is very helpful in focusing on the eventual goal over daily variations—something that Wii Fit really should have taken into account, I feel.
