composition: Op. 25 No 11, Etude in A minor

b1 in GC (→GE)

g1 in FE & EE

..

The version of GC (→GE) is almost certainly erroneous – the copyist could have copied it only from one of the remaining Stichvorlage manuscripts, and it is absent both in FE and EE.

In GC and FE there is no  returning g1. This patent error was corrected in GE. EE also includes the correct text.

b. 27-30

composition: Op. 25 No 11, Etude in A minor

..

In the passages including a few octaves, there are no accidentals in the sources, which, however, does not raise doubts concerning the text intended by Chopin.

In GC there are no sharps needed in the notation of f1f2 in bar 27, ff1f2 in bar 28, f2f1 (L.H.), c1 in bar 29 and fd2 in bar 30.
In FE the same signs apart from the sharps before f1 in bar 27 and f1 (L.H.) in bar 29 were omitted; moreover, the  raising d2 to d2 in bar 29 was overlooked.
GE1 completed the signs overlooked in GC except for the  raising f1 to f1 in the L.H. in bar 29.
In the remaining editions – EE and GE2 (→GE3) – all necessary signs were added.

b. 39

composition: Op. 25 No 11, Etude in A minor

No fingering digit in GC (→GE)

'1' in FE & EE

..

Lack of the fingering numeral over the 6th semiquaver in GC (→GE) is a result of a patent oversight of the copyist.

b. 39

composition: Op. 25 No 11, Etude in A minor

..

There is no accidental before the penultimate semiquaver in GC (→GE1), FE and EE. The missing  returning d3 is undoubtedly an oversight of Chopin, corrected in GE2 (→GE3).
