Lack of the lower octave at the beginning of bar 10 in Ap may point to Chopin's hesitation, as the octave is both in CLI and FE (→GE,EE). The situation in bar 14, in which A1 was added by Chopin only in FEcor (→FE→GE,EE), suggests, however, that the bass note in the original Chopin's idea was supposed to be only A, while the lower octaves were added by Chopin only at the stage of reviewing the entire piece. Overseeing one or two places during this kind of serial corrections would often happen to Chopin (cf., e.g., the Etude in G major, No. 5, bar 4 and analog.). In the entire #Pa Chopin would therefore have left this detail in the original version.
