Wedges & slurs from 2nd quaver in A, contextual interpretation

Whole-bar slurs in GE (→FE,EE,IE)

..

The GE version (→FE,EE,IE), in which the wedges over the octaves at the beginning of bar 10 and 12 were ignored and the entire bars were encompassed with slurs, indicates that the engraver of GE was firmly convinced that Chopinesque slurs were generally careless. However, in this case, adjusting them to clear rhythmic structures certainly does not correspond to Chopin's intention, since in all further appearances of this phrase (bars 193-195 and 376-378) he wrote slurs running from the 2nd quaver in the bar.
It is only the ending of the slur in bar 10 that is to be considered inaccurate; when interpreted literally, in A it reaches only b.

The interpretation of the  hairpin in A, in spite of differing arms, seems quite simple – while writing the top arm, Chopin had to bypass the R.H. chord, hence we assume that it is the bottom arm that determines the intended length of the mark. In GE (→FE,EE) bar 12 opens a new line, which forced the division of the hairpin into two separate marks (it was one of the ways – in addition to the contemporary one – of reproducing hairpins in such situations). IE omitted the first one, probably due to the engraver's inattention.
In EE the cresc. indication in bar 12 was omitted, which could be a simplification of notation or an oversight.

The missing  hairpin could be an oversight or a simplification of notation – the engraver of GE could have considered a third crescendo indication in this bar to be an unnecessary complication.
