In some events, usually teams competitions with International Matchpoint Scoring (IMPs), one makes a further conversion from Matchpoints to Victory Points (VPs).
The conversion occurs on a match- by-match basis. The purpose is to reward large victories more generously than small ones but to limit the extent of very large wins to prevent the result in one match effectively determining the outcome of an entire tournament.
In a Swiss teams competition, it is common for the VP scale to go from 0 to 20, with 20 being a maximum win and a score of 10 for a tied match.
