I think what you call "Strong SSA", Nick calls "SSA with observer-moments
as the reference class". One of his papers is supposed to have a
discussion of whether the reference class should consist of observers or
observer-moments, but I am unable to find it. (Nick, if you're reading
this please point us to the paper.)
