We consider that the  hairpins in AI and AF are of the same range – the mark begins over the d1 crotchet in AI, and under the f1 minim in AF, hence in both cases on the 2nd beat of the bar. In GE the mark is a reversed long accent at the beginning of b. 9, yet it is highly likely that it was reproduced inaccurately due to the transition into a new line, starting from b. 9 – an earlier beginning is particularly indicated by its placement in GE1. Therefore, uncertain as to the exact range of the mark in [AG], in the main text we convey the hairpin after AF.
The version of FE is inaccurate, whereas the one of EE – erroneous.

b. 8-9

No slur in AI & FE (→EE)

d-G slur in AF & GE

..

The absence of a separate slur for the bass voice is most probably an oversight of the engraver of FE (→EE). The slur (as well as the staccato dot over G) is also absent in AI – cf. the note in the upbeat.

Overlapping slurs in FE (→EE)

..

In AF both the ending of the slur in b. 8 and the beginning of the slur in b. 9 are written inaccurately, as a result of which each of the given versions may be considered an interpretation of this notation. According to us, the latter is to be interpreted as beginning from the 1st quaver of the bar, which is indicated by the similar yet more accurate versions of notation of AI and AF in analogous b. 100-101 (in AF the version prior to combining the slurs). To the main text we adopt the version of FE, perhaps proofread by Chopin (the first slur having been extended). The version of AI and GE may be considered an equal variant.
