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

Notation in keeping with Chopin's understanding of this figure

..

In bar 5 in GE (→FEEE) the semiquaver in the figure  is moved to after the third note of the triplet in the accompaniment, similarly in bars 9, 11 & 13. This inauthentic notation, misleading for the performer, was used throughout the Nocturne – cf. bars 15, 51, 88, 89.

See the chapter devoted to this topic in: Jan Ekier, Introduction to the National Edition, Editorial Issues.

Accent in EE

..

The accent in EE is certainly an arbitrary addition by the publisher, introduced by analogy with an authentic accent in similar bar 89.
