The letters represent an age category, rating group, gender, and weapon. The last number is a count of how many of these series events have taken place over the course of the season.
Y10XE2 = Youth 10 Mixed Epee 2
DV2WF1 = Division 2 Women’s Foil 1
You can find a full list of these codes on our Series and Events Page.
