To me "league" sounds more like an "organization of sports teams which play against one another for a championship" than a "group or association of cooperating members". (From Wiktionary.) Maybe LP is planning to run some sort of series of regattas in the near future. (To which my reaction is like Rob's: who cares?)
Not commenting on the fundamental impossibility of meaningfully comparing performances in different places and at different times, but for LP, "Plaqued Laser" and "Club Laser" (Capitalized!) seem to be intentionally different products now.
