b. 31-32

composition: Op. 10 No 9, Etude in F minor

..

In both bars AI features a1 as the 5th semiquaver (the note is written only in bar 31, as bar 32 is briefly marked as repetition of the previous one). This pianistically and sonically awkward version is certainly a mistake, which is revealed by the compatible version of the remaining sources, as well as the comparison with analogous bars 35-36.

b. 33-34

composition: Op. 10 No 9, Etude in F minor

..

Before the 9th semiquaver there is no  raising e1 to e1 in AI (the notes are written out only in bar 33, as bar 34 is only briefly marked as repetition of the previous one). It is a patent inaccuracy, which is confirmed by the compatible version of the remaining sources, as well as the comparison with analogous bars 29-30.

Long accent in AI

Short accent in A (→FE→GE,EE)
..

The accent in A may be regarded as short, and that is how it was reproduced in the editions. However, the mark is shifted to the right of the note which suggest the intended use of a long accent. A clear long accent is written in AI.

b. 45-48

composition: Op. 10 No 9, Etude in F minor

..

In AI this phrase is not preceded with octaves. Chopin marked their use only from bar 49.
