Does it matter if I win or lose 3-0, 3-1 or 3-2? And does the individual game score matter?
The overall match score does impact the rating calculation. For example, 3-0, 3-1 or 3-2 match results all have different effects on player rating changes. A 3-0 win is considered stronger for the winning player than a 3-1 win or 3-2 win.
Individual game scores do not have an effect on the rating calculation - e.g., a 11-0, 11-0, 11-0 result is treated the same as a 11-9, 11-9, 11-9 result.
