RETENTION
Who came back this season
Of the swimmers who swam for Madison Mariners in 2024-25 — how many are here in 2025-26
10 & undersample too small (2 < 6)
— · 2/2 11-12sample too small (5 < 6)
— · 5/5 all NJ clubs pooled (92% overall)
The mid-teens drop-off is sport-wide, not one club’s story — read every row against the NJ marker, never in isolation. Age groups are the swimmer’s age at the end of 2024-25; swimmers with no birth date on file are counted in All ages only. Membership is counted from published swims, so a swimmer who hasn’t raced yet in 2025-26 still counts as here while the roster carries them.
MEET CADENCE
How much this club races, and at what level
Distinct meets the current roster swam at — counting meets, never scores
Meets are attributed through the current roster’s published swims, so a season a swimmer raced before joining Madison Mariners counts toward the meets they attended then. Numbers describe; they do not rank.
