The sources differ in the shape and placement of the accents on the 2nd beat of those bars (in JC there are no signs here). As far as the graphics is concerned, the authenticity of both vertical accents placed in PE above the upper pentagram and common accents between the pentagrams in EF does not raise any doubts – Chopin would frequently use both types of notation. In this context, they basically indicate the same performance, as the signs placed in both the first and second positions are to be considered as referring to the parts of both hands.
