The EE pedalling, however formally correct, raises doubts as for its singling out of the third crotchet in b. 643, which in this tempo is difficult to perform and sonically unjustified. In FE pedal release in b. 645 is surprising as it contradicts the pedaling technique leading to the cumulation of sound of the subsequent chords, which was commonly used by Chopin at the end of his works (but not only there). Pedalling in GC (→GE) must have been omitted (cf. annotation to bars 632-634). For the main text we adopt the pedalling based on FE but without 
in b. 645, whose authenticity we doubt.
