b. 445

There is no  raising d to d in A (→FEEE1). Chopin's patent inaccuracy was corrected by Fontana in FC (→GE); a  was also added in EE2 (→EE3).

composition: Op. 31, Scherzo in B♭ minor

c1-e1 in A (→FC,FEEE) & GE2 (→GE3)

e1 in GE1

b. 450

composition: Op. 31, Scherzo in B♭ minor

b2 in A & EE

a2 in FC (→GE) & FE

..

The version of A is the original one, left by inadvertence: in an analogous situation, eight bars earlier, Chopin changed b2 to a2, and in the discussed bar he introduced an identical change in FC and FE. In the case of FE the change was introduced in the last phase of proofreading, not included in EE.

b. 462

composition: Op. 31, Scherzo in B♭ minor

..

Just like in b. 360, A (→FCGE1, →FEEE1) features a reminding  before g1. The mark, superfluous in this context, was removed in GE2 (→GE3) and EE2 (→EE3).
