Re: Moving average
There are three basic approaches to running sums & averages---user variables, self-joins, and app-level logic. User vars have their limitations. Self-join approaches bog down with big tables. Both need more normalisation than your tables manifest. So given what you have, I would think app-level logic is caled for.
