b. 91

in A

No indication in FE (→GE,EE)

..

According to us, it seems more likely that con forza written in A was overlooked in FE (→GE,EE).

b. 92

composition: Op. 10 No 8, Etude in F major

Fingering '5' in A

No fingering in FE (→GE,EE)

..

Lack of the fingering digit in FE (→GE,EE), which was clearly written in A, is most probably a mistake. The not very legible mark visible in A over the 1st note in the R.H. may be the digit '1'. Having no certainty of this, we consider it, as the use of the 1st finger in this place is beyond any doubt.

Fingering in A

FE (→GE)

..

The fingering of A is inaccurate, while in the L.H. it is certainly superfluous. In the main text we give the completed and corrected indications of FE (→GE).

composition: Op. 10 No 8, Etude in F major

 in A

FE (→GE,EE)

The fact of moving  from bar 93 to 94 is most probably a result of Chopin's proofreading of FE (→GE,EE).

b. 94

composition: Op. 10 No 8, Etude in F major

..

In A there is no  raising c1 to c1. This patent inaccuracy was corrected in FE2, GE and EE.
