Since a 3-point moving average filter is simply (t1 + t2 + t3)/3.

Your coefficient set would be:

Time . . Coeff.

1. . . . 0.33333

2. . . . 0.33333

3. . . . 0.33333

You can create a text file with the coefficients and import it into the megawizard (edit coefficient set, bottom of the window there is a radio button for import from file)

(edit - sorry, I'm having a heck of a time making the table look like a table)
