b. 20-40

composition: Op. 10 No 3, Etude in E major

..

In FE (→GE,EE) Chopin abbreviation rall. in bar 20 was extended to rallent. 

In AI the indication is completely absent. Due to the working character of AI, we do not consider the lack of this and other performance indications as an equal version of a given fragment. In particular, when AI is not mentioned in the text of the note, which means that the discussed indication is not included in it.

b. 20-21

composition: Op. 10 No 3, Etude in E major

Slur in A & GE2 (→GE3GE4GE5)

Slur in FE (→GE1,EE)

..

The shorter slur of FE (→GE1,EE) is certainly a result of a too literal interpretation of A. Moreover, in FE (→EE) the slur was placed under the stave. The graphic layout of GE is similar to A in this respect.
See the note at the beginning of the bar.
