The analysis of the 
or 
markings, written by Chopin in A in these and analogous bars, leads to the conclusion that, despite significant differences in length (from a long accent to a two-bar hairpin), all of them most probably denote long accents. Due to that reason, in the main text we decided to unify them; we adopted a compromise marking, which is more or less one-bar long. In the remaining sources Chopin did not interfere with the shape of those markings.
