In A (→FC,FE1) there are no accidentals before the last semiquaver (in both hands), which, when interpreted literally, gives d1 and d. In FE2 was added, yet only in the R.H., where it is a cautionary accidental. GE and EE include naturals in both hands.

In A (→FCGE) there are no naturals before d2 and b1, since Chopin considered the previous accidentals before d3 and b2 to be valid. In FE (→EE), in which the first part of the roulade was written without an octave sign, respective naturals were added.

The lack of naturals before the sixth on the 6. quaver is an undoubted oversight by Chopin in A (→FE). The  before the upper note was complemented in both GE and EE, however the one sharpening d2 to d2 was only added in GE2 (→GE3GE4). The lack of the latter accidental also infuences the pitch of the penultimate quaver of the bar. This inaccuracy was noticed during the proofreading of FE (→GE,EE) where a  was added before that quaver.
