It is difficult to say whether the change of indication introduced by GE (→FE,EE) was a result of the engraver's inattention, revision or even Chopin's proofreading. The change seems too insignificant to bother about, which eliminates the last two possibilities. According to us, we can take one other scenario into account, maybe the most likely – the visible traces of corrections in the L.H. part reveal that the parts of both hands were initially misaligned (while planning the L.H., the engraver did not take into consideration the final R.H. quaver). Had leggieriss. been in the area of the correction, the engraver could have then inaccurately reproduced it from memory.
