In the main text we give the version of GE, which is probably later. In AF one can see that the hairpin blends with the L.H. slur, which could have prompted Chopin to use a verbal indication in [AG]. In FE the hairpin breaks at the end of the line, in b. 74, which EE reproduced in the simplest way possible by inserting a complete mark of such a range.

The  hairpin in AF seems to be inaccurate, since it overlaps with the  mark, which concerns the same phrase. Moreover, it was already considered inaccurate in FE (→EE). In the main text we give the mark of GE, compliant with the remaining editions.

In the main text we give the  hairpin written in AF. One can have doubts whether the mark should not be placed earlier, before the return of the main phrase of this section, the way it was reproduced in FE (→EE).

 under or after 3rd crotchet in AF, contextual interpretation

after 3rd crotchet in FE (→EE)

under 3rd crotchet in GE

..

Once again, like in analogous b. 45-57, the  marks are placed in AF under or after the 3rd crotchet of the bar. However, their placement is not explicitly linked to the harmonic content of the chords – marks after the 3rd crotchet are to be found in, e.g. b. 77 and 79, in which the chord changes to E major on the 3rd beat (in the substantive transcription we move them under the 3rd crotchet). FE and EE standardised the position of the marks yet without taking into account harmonic changes, which must be a result of inaccuracy of the engraver. In the main text we reproduce the consistent and reasonable notation of GE.
B. 86-87 are discussed separately.
AI is devoid of pedalling markings here.

Pedalling in AF (→FEEE)

Pedalling in GE

..

The shorter pedal of AF is the original version, left here most probably by inadvertence (b. 103 opens the page) – in analogous b. 11-12 Chopin changed this pedalling in AF to the one featured here in GE.
In FE (→EE) the  mark was placed slightly earlier, which is irrelevant in this case.
