The majority of the sources are missing some of the necessary cautionary signs (flats), which, however, only to the minimal extent impedes the correct interpretation of the text. As it can be concluded from the notation of FE, probably the closest to the notation of [A], Chopin generally omitted the sign next to the note, which already appeared in the same bar, with a relevant sign, one octave lower or higher (in the discussed fragment, FE lacks 12 flats). In GC and EE1 the notation is more precise, further additions were also introduced in EE2 (→EE3), yet only GE has a fully correct text. Similarly in bars 25-28.
