There is no accidental before the penultimate semiquaver in the majority of the sources. When interpreted literally, it is a d
3 due to the 
before the 2nd semiquaver. This version, inconsistent notation (e2-d3) aside, implements the harmonic scheme of such figures in bars 315-318, using chord elements only, and we give it as such in the main text, adding a reminding before the discussed note. However, one cannot exclude an oversight of the alteration's cancellation by Chopin, which is one of his most frequent mistakes. The version with d
3, resulting from such an assumed mistake, continues the melodic and pianistic scheme defined in the two previous figures, which we suggest as an acceptable variant.
