In the main text, we place a demisemiquaver under/over the last note of a semiquaver triplet in each of the 4 places where such a combination occurs, in accord with the notation of A (→GE→EE,FESB). In FE1 (→FE2) the demisemiquaver in these figures is placed after the last semiquaver of the triplet. This is certainly an arbitrary revision of the engraver of this edition, who had not yet seen that Chopin was using this Baroque-Classical convention, which in the 19th century was gradually superseded by a notation conforming with the strictly calculated nominal rhythmic values of the notes.
Chopin would use that convention throughout his entire oeuvre – see the chapter dedicated to that issue in: Jan Ekier, Introduction to the National Edition, Editorial Issues, p. 183.
In all places (as well as in bar 44) AsI notes a dotted rhythm in twice the rhythmic values, as 
. This is an obvious mistake.
