Thanks for catching that problem.  In referring to Shanks & Pottenger
(2003) I see that the actual error was worse than that: the last two
columns of those lines were reversed.  (It's the sort of mistake that
one might expect of me -- I'm in the wrong hemisphere!)

I'll fix things as follows in my next proposed patch:

Rule   Uruguay 1941    only    -       Aug      1       0:00   0:30    HS
Rule   Uruguay 1942    only    -       Jan      1       0:00   0       -
