In A, the grace note is so close to the f4 quaver that the 8 digit opening the octave sign, although actually placed over f4, encompasses the grace note too. In spite of that, FE (→GE,EE) clearly excluded the grace note from the octave sign, which is, according to us, a mistake, since it constitutes a sonically unjustified complication. Such a problem with a grace note and an octave sign is also to be found in other pieces by Chopin, e.g. in the Sonata in B minor, Op. 58, 4th mov., b. 254 and 258, where it seems that the grace notes are not encompassed with the octave sign in both places, yet the pianistic context (and in b. 254 also the musical context) is an argument for inaccuracy of notation.
