b. 69-70

composition: (Op. 4), Sonata in C minor, Mvt II

..

In the main text we omit the poorly justified cautionary flats in bar 69 (to c1) and 70 (to d1), present in all sources.

b. 69

composition: (Op. 4), Sonata in C minor, Mvt II

Long accent in A, possible reading

Short accent in GE (→FE,EE)

No mark in IE

..

The accent mark in A is longer than the one in bar 65, hence we reproduce it as a long accent. However, it is also likely that this difference is of a random nature, while the interpretation compliant with Chopin's intention is the one adopted by GE (→GEFE,EE).
The absence of the mark in IE is most probably an oversight.

b. 71-72

composition: (Op. 4), Sonata in C minor, Mvt II

f1 tied in A (→GEFE,IE)

f1 repeated in EE

..

In GE (→FE,IE) both the R.H. slur and the R.H. tie were inaccurately reproduced – there is no ending thereof in bar 72, in a new line. In our transcriptions, we interpret this version as compliant with A. In EE the slur was reproduced correctly, but the tie to f1 was omitted. In the main text we provide the unquestionable A notation.

b. 72-74

composition: (Op. 4), Sonata in C minor, Mvt II

2 slurs in A

Continuous slur in GE (→FE,EE,IE)

..

The adjacent endings of the slurs at the beginning of bar 73 are so close to each other in A that it cannot be ruled out that Chopin wanted to combine them. On the other hand, if this had been the case, he could have simply drawn one slur (under the notes) or add a second one, also under the notes, to emphasise their continuous nature. Therefore, the difference in the position of the slurs suggests the solution adopted to the main text, that is 2 overlapping slurs. This is also confirmed by the distribution of voices – the crotchets in bar 73 enter as a new, third voice.

Slurs over triplets in sources

No slurs, our suggestion

..

In bar 73, 75 and 77, in the main text we omit the slurs being part of the triplet markings – cf. General Editorial Principlesp. 16. In this case, there are no doubts that this is the only function of these slurs, which is confirmed by the staccato marking in bar 77.
