The authenticity of the dotted rhythm in GC (→GE) and EE does not raise any doubts. The equal semiquavers of FE may be considered as a result of inattention of the engraver or misunderstanding of the handwritten base text, yet the version can be also a result of Chopin's correction, introduced still in the manuscript or proofreading of FE. As one of the traces of possible changes performed in print, one can consider the too long slur, adjusted to the note being closer to the bar line than the visible g semiquaver.
