b. 201

composition: Op. 22, Polonaise

b2-a2 in FE

a2-g2 in GE & EE

..

Similarly as in the case of b. 57, the version of EE and GE is an earlier version of this place, left contrary to Chopin's intention. See also the note in b. 200.

b. 201

composition: Op. 22, Polonaise

..

The sources are lacking in the accidental before the 2nd played note of the run, which must be Chopin's mistake.

b. 203-204

composition: Op. 22, Polonaise

..

Just like in b. 59-60, EE are lacking in both flats lowering d2 to d2 and in the cautionary  before d3. Chopin added all three accidentals only just in the last stage of proofreading of FE (→GE); they are also in EE2.

b. 205

composition: Op. 22, Polonaise

..

In FE (→GE), there is no  restoring d2 on the 6th note of the run (like in b. 61). In turn, the mark is present in EE, unlike in b. 61, in which both this mark and the  restoring e2 two notes later are absent. It suggests that the  restoring e2 in b. 61 and 205 was added in FE in the last stage of proofreading, not included in EE, and that the reviser of EE added two naturals only in b. 205. However, there are no visible traces of correction in FE that would confirm the above assumption.

b. 206

composition: Op. 22, Polonaise

c3 in FE (→GE)

a2 in EE

..

Like in b. 62, the version of EE is most probably the initial version or a mistake, corrected then in FE (→GE).
