in GC, EE & GE2 (→GE3)

in FE & GE1

The use of the  time signature is surprising only in GE1, as FE did not use the  indication in the Etudes – contrary to the manuscripts – even once, neither in Op. 25 nor in Op. 10 and in the Etude in F minor, Dbop. 36 No. 1 (cf. also the Impromptu in A major, Op. 29). Anyways, the correctness and authenticity of the  time signature is undeniable with respect to the compatible version of GC and EE.
The correct time signature returned in GE2 (→GE3).
Similarly in bar 104.
