b. 640-641

No sign in A (→FCGE1, →FEEE)

 in GE2 (→GE3)

..

Similarly to b. 189-190, GE2 (→GE3) arbitrarily added a  modelled after b. 57-58.

In A nad FC, this bar is a replica of b. 193, and likewise there we regard the shorter  sign as possibly inaccurate. For that reason, in the main text we give a longer hairpin, modelled on b. 185.
The absence of the sign in GE2 can be explained by an oversight or a revision, aiming to make this bar uniform with the analogous b. 636. GE3 restored the .

b. 645

composition: Op. 31, Scherzo in B♭ minor

Staccato dot in A (→FC)

No mark in FE (→EE) & GE

..

As in b. 637 and 639, we consider the staccato dot over b2 a remnant of the original version, presumably removed during the proofreading of FE (→EE). However, the absence of mark in GE is most probably an oversight by the engraver.

b. 648-649

composition: Op. 31, Scherzo in B♭ minor

Two-bar  in A (→FCGE)

One-bar  in FE (→EE)

..

In the manuscripts these bars are marked as repetition of b. 197-198. In spite of that, FE (→EE) reproduced the  mark differently than before, inaccurately.

No markings in A (→FEEE)

Pedalling in FC (→GE)

..

In the main text we give the pedalling entered by Chopin into FC (→GE) in b. 197-206 and valid also here due to the abridged notation of the discussed bars.
