The values of the metronome tempo, both 120 in A and 160 in FC, were written with Chopin's hand, it was most probably also the case in the manuscript base text to EE. Therefore, in the main text we give 160, present in two authentic sources.

The second chord in the R.H. is a crotchet both in the upper and lower voices. Hence the lower voice has 9 quavers in this bar. The error resulted from hastily performed articulation corrections – Chopin would delete the staccato signs written inside the chords, which, in some cases, required rewriting the entire chord; omission of the quaver flag occurred exactly in the last rewritten chord.

In all sources, except for GE and EE2 (→EE3), there is no  returning g1 in the 3rd chord in the R.H. It is a characteristic for Chopin, patent inaccuracy (in analogous bar 8 Chopin wrote a relevant sign in A). In GE was added also before g2.

The seemingly erroneous notation of A and of the remaining sources (except for GE2 and GE3) could have been intended by Chopin, although in this Etude, he used the notation compliant with the rules in similar cases. In other pieces, rhythmic values exceeding the bar were used by Chopin both in autographs (e.g., the Concerto in F minor, Op. 21, 1st mov., bars 278-279, 3rd mov., bars 423-424) and corrections of print (the Polonaise in C minor, Op. 26 No. 1, bars 19-20). On the other hand, one cannot exclude a simple oversight of the quaver flag (cf. bar 15).
