When interpreted literally, the fingering in FE raises doubts due to its problematic purpose – the 5th finger on D
is most obvious in this context and it is difficult to imagine why Chopin would have wanted to indicate its use right here. According to us, the engraver assigned the digit to a wrong note, hence in the main text we place it under d, where such information is useful.
In EE, Fontana, as well as in a few other places (e.g. in bar 79), copied the change of fingers to d, which, in the light of the authentic articulation, staccato on D, is a totally unjustified complication.
