Underrate(UR) is your Pair Rating less the Pair Rating equivalent of your
Masterpoints. To find this equivalent, consult
the Master
Point to Power Rating conversion chart. Find each partners Masterpoints in the left column.
Masterpoints are converted into Power Ratings in the right column. The Power Ratings are averaged
to get the Pair Rating. Since we are more familar with Masterpoints, the results are presented in
terms of Masterpoints. (PR/MPs) is your Pair Rating converted to Masterpoints, a tricky
situation. Each partners Power Rating is used. If a partner is not rated, his/her Masterpoints
are converted to a Power Rating. Then the Pair Rating is split in the same ratio as
the Power Ratings. The resulting splits are doubled before they are converted to Masterpoints.
If a partner has no Masterpoints the pair is neither underrated or overrated.
