Rhythmic notation in FE

Our suggestion

..

The notation of the octave c2-c3 in FE and GE is certainly inaccurate, which was corrected by the reviser of EE. The extension of the sound of the quaver a2 is written only in GE. It was introduced by Chopin in [A2], certainly in order to make the notation more precise, therefore, we consider it in the main text.

FE1 and GE are lacking the  lowering dto d1. This patent inaccuracy was corrected in FE2 and EE. Moreover, in FE1 there are no naturals before two last quavers in the L.H.; the remaining sources have a correct text.
