a in AI, GE & EE

in A (→FE)

..

The version of A (→FE) is almost certainly erroneous. It is revealed by the notation of AI in this bar and a compatible version of all sources in analogous bar 44. The correct text of GE and EE is most probably a result of revisers' actions, probably on the basis of comparison with bar 44.

b. 31-32

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

..

In both bars AI features aas 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.
