How to Compute a WAVE
A racer's WAVE (weighted average) is computed using the last three meets and the number of meet points the dog scored. You need to know whether the meets were complete or incomplete. Although there are several ways for a race to be incomplete (DNF, OC, DQ, SCR, PSCR)*, you only need to know whether the dog ran a complete or an incomplete meet to figure the WAVE. The grading guide shows a "y" for an incomplete meet.
Here are the rules for computing a WAVE:
1. A dog has three complete meets  the formula is [(complete meet1) + 0.7(complete meet 2) + 0.5(complete meet 3)]/2.2  where meet 1 is the most recent complete meet.
2. A dog has two complete meets  the formula is [(complete meet 1) + 0.7(complete meet 2)]/1.7  where meet one is the most recent complete meet. If the dog has two complete meets and one incomplete meet, disregard the incomplete meet and use this formula.
3. A dog has one complete meet  the WAVE is the meet points earned in that meet. If the dog has one complete meet and two incomplete meets, disregard the incomplete meets.
4. A dog has one incomplete meet  the WAVE is the meet points earned in that meet;
5. A dog has two or three incomplete meets  the WAVE is the average of the scores. Add the meet points up and divide by either 2 or 3 depending on the number of meets  that's your WAVE.
* DNF  did not finish; OC  off course; DQ  disqualified; SCR  scratch; PSCR  paddock scratch.
If your eyes glaze over when you look at the formulas, see the handy Excel worksheet above that will do the work for you.
