The use of  time signature surprises only in GE1, as in FE the  indication was not used in the Etudes – contrary to the manuscripts – at all, neither in Op. 25 nor in Op. 10 and the Etude in F minor, Dbop. 36 No. 1 (cf. also the Impromptu in A major, Op. 29). In any case, the correctness and authenticity of the  time signature is unquestionable due to the compatible version of FC and EE. The correct time signature was returned in GE2 (→GE3).

b. 1

composition: Op. 28 No. 17, Prelude in A♭ major

..

In A one can see that Chopin initially wrote  to mark the time signature on both staves. Moreover, the eventually left 6/8 reveal (also on both staves) minor crossings-out, which seem to be digits preceding the digits 6, although it is difficult to guess what their meaning could be. Anyways, it is an example of Chopin's hesitation, since the time signature in FCI, which was written earlier, is 6/8, like the final version.
