The cautionary  to a1 is present only in FE (→EE), perhaps added by Chopin in the stage of proofreading FE. In the main text we also add a  to a in the L.H.

In FC both poco a poco cresc. - - - indications (in bars 17-23 and 25-31) are added in Chopin's hand, which means that they were also added in the stage of proofreading FE or to the basis of FE. The same in bars 49-55 and 57-63.

Rest in FC (→GE)

No rest in FE (→EE)

..

Completing the R.H. top voice with a rest on the 3rd beat in the bar is an example of ultra-correct notation, used by Chopin only exceptionally, and in this case even misleading – f1 in the last crotchet, belonging allegedly to the bottom voice, is actually a beginning of the next phrase in the top voice. In the main text we omit it, since it could have been added by Fontana or removed by Chopin in the proofreading of or in the basis for FE.
A similar situation is present in bar 56.

The improved voice leading, achieved by avoiding parallel B-f and c-g fifths, most probably resulted from the Chopinesque proofreading of FE (→EE). The fact that this version appears in GE2 suggests the use of FE in the revision of this edition.

This is the most significant difference between the authentic sources – FC and FE – in entire opus 30. The FE (→EE) version, which is a clear improvement of the Mazurka ending, must have been introduced by Chopin in the proofreading of or in the basis for FE instead of the FC (→GE) version.
