The moment of beginning the 
hairpin in A intended by Chopin is unclear. The sign starts clearly before the bar line of bar 206, the first one on a new page, which suggests that it began still in the previous bar; however, it does not allow to determine the precise location of the beginning of the sign. GE1 (→FE→EE) considered it simply an inaccuracy, which could be right. GE2 adopted a solution similar to the one adopted to the main text – beginning of the sign after the last note in bar 205.
