Past results are not indicative of future performance

I'm trying to milk the Stalk Market in Animal Crossing Wild World. What better way to predict trends than collecting data about the buy rate. I see Tom Nook at least two times a day now:

As I said, when it hits 200 I intend to cash out. "Last week" was a total bummer, never rising above 100. Then again it was "Flower Fest" the whole week.

I'm going to try to collect more data and update this graph.
