Crotchet & quaver g2 in AsI

Extended crotchet & semiquaver in remaining sources

..

As was the case with b. 69, in the majority of the sources (except FESB) the syncopated g2 crotchet is prolonged with two dots, which leads to an excess of rhythmic values – 5 quavers in the bar. The mistake was noticed and corrected (awkwardly in terms of graphics) only in FESB.

b. 79

composition: Op. 28 No. 15, Prelude in D♭ major

..

A (→FCGE1) gives 9 as the number of notes in the irregular semiquaver group (instead of 10). The mistake was corrected in FE (→EE) and GE2.
See also bar 4.

Slur to f2-a2 in AI

2 slurs in FE (→GE1,EE)

Slur to c2-e2 in GE2 (→GE3)

It is difficult to say whether the shorter slur of AI defines an actual variant of articulation of this motif or – which, according to us, is more likely – whether it is inaccurate or erroneous (e.g. written with bar 81 in mind). The additional, short slur in FE (→GE1,EE) is most probably a mistake, perhaps caused by unclear notation of [A] (e.g. a correction to the rhythm and slurring present in AI two bars later). Its presence next to the longer, undoubtedly correct slur therefore probably resulted from the fact that the engraver did not finish implementing the corrections Chopin introduced while proofreading FE1 (the engraver added the correct slur, but did not remove the erroneous one). The shorter slur was considered erroneous and omitted also in GE2 (→GE3).

b. 82

composition: Op. 16, Rondo in E♭ major

In FE (→GE,EE), there is no  restoring f2. Such missing cancellations of previous alterations belong to Chopin's most frequent mistakes. There is a similar situation in bar 234.
