b. 4

composition: Op. 10 No 2, Etude in A minor

..

In CLI and EE2 the  returning d1 on the 4th beat of the bar was deleted, which is a patent error. In CLI there is a superfluous  before gin this chord, which shows that Chopin did not include in the notation the previous alterations in this bar at all. Similarly in bar 12.

b. 5

composition: Op. 10 No 1, Etude in C major

b3 in CLI & EE

a3 in FE (→GE)

..

The b3 note on the last semiquaver of CLI and EE could be easily considered as a mistake except for the fact that in analogous bar 53 the sources have the same text. Therefore, it cannot be excluded that in CLI we are dealing with the original version, while in EE with the editor's revision.

b. 5-6

composition: Op. 10 No 1, Etude in C major

..

In CLI the G1-G octave in bar 5 is a semibreve, while the D1-D octave in bar 6 – a minim. It seems to be highly unlikely for this obvious error to be included in [AI].
