In the version of GE1 (→GE2), the first 4 notes and rest constitute an unmarked semiquaver quintuplet. Nothing points to authenticity of that version, although it is practically very close to the actual performance – see the commentary to the Scherzo in C
Minor, Op. 39, bar 47. The version of GE3 was probably introduced on the basis of analogy with similar bars of exposition.
Like in bar 197, 199 and 201, in FE one can see traces of swapping rhythmic values of the 2nd and 3rd notes – initially, the 2nd note was a semiquaver, whereas the 3rd one – a demisemiquaver.
