I meant 'trained' networks in contrast to totally-synthetic intentionally-pathological networks like my 2abs-1 example. (It could be that only pathological cases give bad results - similar to how (Hindley-Milner) type inference is EXPTIME-complete but works fine for ~all real world programs - but that seems unlikely.)
