b. 89

composition: Op. 27 No 1, Nocturne in C# minor

GE (→FEEE): semiquaver after the last note of the sextuplet

Notation in keeping with Chopin's understanding of this kind of figures

..

We align the semiquaver on the 2nd beat of bar 89 with the last quaver of the L.H. sextuplet although in this particular context an exception to the general rule could be admitted. Only a discovery of additional sources—e.g. [A] or an annotated copy—could assist in establishing Chopin's intention more firmly.

b. 89-97

composition: Op. 27 No 1, Nocturne in C# minor

GE (→FEEE): semiquaver after the last note of the sextuplet

Notation in keeping with Chopin's understanding of such figures

..

In bars 89, 91-95 & 97 GE (→FEEE) moved the semiquaver in  beyond the 3rd note of the triplet in the accompaniment, contrary to Chopin's understanding of that figure.

b. 96-97

A tie for bin GE

No tie in FE (→EE)

..

Missing in FE (→EE) is the tie sustaining bin bars 96-97, certainly due to oversight.
