According to us, the 
hairpin written in A1 is to be interpreted as ending before the 
indication in b. 13. It is most likely that Chopin first wrote the top arm (perhaps before entering ) and then indicated the end of the mark with the ending of the bottom arm. Such an interpretation is confirmed by the mark of A1 in b. 36 and the notation of GE based on [A2] (in GE2 the mark was shortened with respect to GE1, which does not influence its meaning). In FE the mark was interpreted according to the length of the top arm; moreover, FE2 reproduced it inaccurately. It remains unclear how come that the mark was shortened in EE – perhaps by analogy with b. 36.
