The  time signature is most probably an error or FE's and GE's revision. Changes of time signature indication of that kind are to be found on a number of occasions also in other Chopin's pieces issued by those publishing houses – cf. e.g. Etude in C, Op. 10 No. 1, bar 1..

We give the time signature's indication after CLI. Although FE (→GE,EE) has a , it is difficult to assume that the change of time signature was intentional, as in FE the indication  does not appear in any of the Etudes (contrary to the manuscripts), cf. the Etude in C minor, No. 4, F major, No. 8 and C minor, No. 12. This phenomenon is also present in other pieces, even in the most obvious cases, e.g., in the Etudes in F minor, Op. 25 No. 2, D major, Op. 25 No. 8 or F minor, Dbop. 36 No. 1.
