1) Standard
... 10) 1-26
All these have a Nationals. So, JJ missed a few.

Technically, the 1-26 Association makes it own rules for its (international)
Championships, not SSA, let alone FAI, although I take the broader sense of
"we" and "having" a Nationals, in which case you might even go on to Vintage
(VSA), Aerobatics (IAC/EAA) or Intercollegiate (CSA -- ask me about it)...
I really only bring this up to point out that, by contrast, SSA does have an
official Nationals scheme for FAI-inspired X/C soaring classes...

11) Juniors (including Rudy Mozer Champion trophy)
12) Women
with "the" Nationals being a pseudo-contest of best scores obtained at ANY
SSA-sanctioned Nationals (past Junior Champions have done their thing in
World Class, Sports, 15m, Std...).
