As and AI, in which bars 49-64 are not written out, have here the version with a rest on the 3rd beat of the bar, repeated after bar 37. The version with a repetition of the fifth, written in A and in the editions, was the first that Chopin wrote at all, since in As one can see a deletion of a fifth in this place. The Chopin intention of differentiating certain details of the accompaniment finds confirmation in a similar difference between bars 44 and 60.
