The use of 
time signature is not surprising only in GE1, as FE does not use the 
indication in the Etudes – contrary to the manuscripts – at all, neither in Op. 10 nor in 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 does not raise any doubts thanks to A (→FC). The correct time signature was returned in GE2 (→GE3).
