It is hard to state how the difference in the placement of 
occurred and, which is more important, which note it is supposed to concern – the C
grace note or the e1 minim. The compatibility of GC and EE (
is almost certainly a result of a misinterpretation of ) allows to assume that in the manuscripts the sign was under the stave, which would rather indicate the mnim. The version with minim is also supported by deletion of the concerning it accent in GC, considered by Chopin as superfluous, perhaps due to . We give this version in the main text, present in the base source and including the Chopin correction.
On the other hand, the indications of FE – under C and accent over e1 – have a musical sense, particularly in the context of corrections of the dynamics in the previous bar. Therefore, we recommend this version as alternative with respect to the main text. At the same time, we interpret the accent as long, taking into account the sign that the copyist rewrote in this place from GC, as well as the one Chopin added in FES in bar 1.
