GC and the previous impressions of FE (→EE) include the erroneous f as the top bottom note in the chord on the 2nd crotchet. The mistake was revised in GE, adding a 
before this note, which has to be considered to be justified. However, the comparison with analogous bar 171, and, above all, the change introduced – probably by Chopin – in FE4 convinces that the mistake concerned the pitch and not the missing . The version with e
was introduced also in EE2, most probably on the basis of FE4. According to us, both here and in the previous bar, we are dealing with Chopin's mistakes in [A].
