The differences in the range of the 
hairpin could be stemming from the notation of [A] – Chopin would often write these marks inaccurately, with arms of different length. A comparison of both sources controlled by Chopin in both analogous places (here and in bars 87-89) reveals three different kinds of range, out of which one occurs twice, in FE in bars 17-19 and in FC in bars 87-89. Taking into account the fact that a mark provided with such range can be found in both places and both sources, we consider it to be most representative and give it in the main text.
