b. 35

composition: Op. 29, Impromptu in A♭ major

 
 
..

In EE the pedal was already placed at the beginning of the bar, earlier than in the remaining sources. It can be a result of ambiguous notation of the manuscript - the base text of EE.

b. 37

composition: Op. 29, Impromptu in A♭ major

 
 
..

The  sign in A may be interpreted in 2 ways:
– as referring to the minim b1 in the R.H.; the sign in bar 35 is similarly placed (in reference to the crotchet F);
– as referring to the note E on the 2nd crotchet of the bar; such an "anticipating" notation can be seen on a number of times in A, e.g. in bar 38.
The sign in EE raises similar doubts. 
We consider the placing of the sign under the 2nd crotchet of the bar as more probable, compatible with FE and GE.

b. 38

composition: Op. 29, Impromptu in A♭ major

..

In EE the  sign is placed too early, under, and even before the 2nd crotchet of the bar. It is certainly a mistake, similarly as the lack of pedalling in GE.

..

In A Chopin deleted the pedal release from the end of bar 65 and put it after the 2nd crotchet. The first version is included only in FE.
