In the main text we give the pedalling of A, since the authenticity of the addition introduced in GE1 (→FE→EE) is uncertain. The doubts are raised by an inaccurate alignment of indications in this bar, the absence of the 
sign in the previous one and a clumsy arrangement of the 1st beat of the bar. If, e.g. a sequence of 
signs at the transition between bars 26 and 27 was originally printed as a whole in bar 27 (considering the 2nd quaver to be the beginning of the bar), Chopin could have added only the most sonically striking mistake, which was the omission of the sign at the beginning of bar 27.
The version of FE, despite being apparently closer to the notation of A than GE1, was most probably forced by the dense arrangement of the text. In GE2 the additional change of pedal was removed, however, the placement of the previous signs was not adjusted.
