The pedalling added by Chopin in a proofreading of FE is inaccurate – the 
mark is between the first two quavers, so we do not know which one it concerns (there is no 
mark at all). In GE and EE the mark was moved (in a different way), so that the moment of depressing the pedal did not raise major doubts – both solutions may be considered as justified suggestions of guessing Chopin's intention. In the main text we prefer the interpretation adopted in EE, as in Chopin's manuscripts the arrangement of the mark before the note is much more frequent than after it (most frequently it is certainly under the note).
