The performance markings of A quite significantly differ from the ones included in FE (→GE,EE). Due to the fact that next to the omission of verbal indications in A the accents in the R.H. in bars 2 and 4 were added, we consider the printed version as proofread by Chopin and we adopt it in the main text. The 
mark in bar 4 is, according to us, written in compliance with a sometimes applied by Chopin convention, according to which the indications are not arranged at the beginning of the area they consider, e.g., a motif, yet closer to its middle.
