The version of FE is earlier – in GC one can see a correction, in which a was deleted, while d1 probably added. A similar change might have been introduced to the base text to EE. According to us, both versions are stylistically more or less equal, and ten years later Chopin did not see a reason to change the original version in pupil's copies.

The g note was added (in pencil) in GC (→GE). Therefore, it is highly likely an addition introduced by Chopin in the last phase of corrections in Stichvorlage manuscripts. The version was adopted in EE3.

In GC, the version beginning from G1 was written by Chopin instead of the original version of FE, beginning from the sixth. This undeniable improvement was also introduced in the base text to EE1, in which, however, it was reproduced inaccurately – both B1 at the beginning of the bar and the lack of tie sustaining d are most probably mistakes. In turn, EE1 includes a dot extending the des crotchet, overlooked in GC. This inaccuracy of the notation of GC was corrected only in GE3, which, thanks to this, is the only source in which the final version is written flawlessly.
The versions of EE2 and EE3 are a result of subsequent revisions – in EE2 it was the version of FE (only in the 1st half of bar 37) that was introduced, whereas in EE3 it was the final version that was reintroduced, yet in an inaccurately written form drawn from GE1.
