Lack of the  returning b2 on the penultimate semiquaver in bars 2 and 6 is most probably an inaccuracy of the notation of CLI. In bar 2 Chopin added the sign in FEcor, in bar 6 – probably already in the handwritten base text for FE.

Lack of the accent in the middle of bar 4 is probably an inaccuracy of the notation of A – it seems highly unlikely that this bar was supposed to be less accentuated than bar 2. In the main text we suggest all accents added probably in a proofreading of FE (→GE,EE). The added accents do not differ from the adjacent ones, therefore, we accept both possibilities of their interpretation – cf. bars 1-6.

The  marks, added by Chopin probably in a proofreading of FE (→GE,EE), are certainly meant to be long accents and this is how we give them in the main text. In bar 2 the length of marks in GE and EE corresponds quite well with the size of Chopin's long accents, although most probably by accident.

The lower notes of the chords on the 2nd and 3rd quavers in bars 2, 6, 10 and 14 were removed by Chopin in a proofreading of FE (→GE,EE). It was probably related to the change of the dynamic concept of these bars. Similarly in bars 50 and 54.

Our suggestion

Our alternative suggestion

..

The pedal markings added in a proofreading of FE in bars 2, 6 and analog. differ in the placement of the pedal release's mark, which in bars 2 and 14 (as well as in 50) is under the 3rd quaver of the bar, while in bar 6 – under the 2nd one. According to us, it cannot be excluded that Chopin had a different vision of pedalling in bars 1-2 and 9-10 (the first bar of the pair without pedal and in the second one, a half-bar long pedal) and a different one in bars 5-6 and 13-14 (all bars with a pedal to the 2nd quavers). We suggest this possibility, in which the  mark in bar 14 must be considered as misplaced, in the main text. As an alternative, we give a homogeneous pedalling in bars 2, 6 and analog., in which  always falls in the middle of the bar (it requires to assume that  in bar 6 was written by mistake).
