b. 207-208

composition: Op. 21, Concerto in F minor, Mvt III

Long accents in A

Short accents in GE (→FEEE)

..

The change of the clearly long accents in A to short ones is certainly a result of an inaccuracy of GE (→FEEE). The sign in bar 207 was initially written over the top stave in A, and then deleted and replaced with an accent between the parts of both hands.

b. 207

composition: Op. 11, Concerto in E minor, Mvt I

No slur in sources

Slur suggested by the editors

..

The missing slur must be considered Chopin's or the engraver's mistake – in the remaining analogous bars, there are slurs, although inaccurate. In the main text, we suggest a slur modelled after the slurs of the sources in bars 205 and 209.

b. 207

composition: Op. 11, Concerto in E minor, Mvt I

..

In FE, a  is only before the top note of the octave on the 2nd beat of the bar. The patent mistake was corrected in the remaining editions by adding a  before the bottom note, whereas in EE and GE3, the unnecessary  before the top note was also removed.

b. 207

composition: Op. 11, Concerto in E minor, Mvt III

No slur in FE

Slur in GE & EE

..

In FE, the missing slur is most probably an oversight related to the introduction of bass clef to the notation of f​​​​​​​. Anyway, it must be an inaccuracy, which was corrected already in GE and EE.
Distraction of the engraver of FE is proved also by the missing initial fragment of the next slur – it is only its ending in bar 208, on a new line, that was printed.

b. 207

composition: Op. 22, Polonaise

 on 4th quaver in FE (→GE1,EE)

between quavers in GE2 (→GE3)

 on 3rd quaver suggested by the editors

..

Just like in b. 63, of which the discussed bar is a literal repetition, the  asterisk was placed a quaver too far in FE, which is probably a mistake.
