in In spite of certain differences in the position and size of the 
marks in A, there is no doubt that they are related to the L.H. minim chords, which allows us to consider them long accents. The way they were reproduced in GE suggests that the engraver wanted to pair them with the R.H. quavers, as a result of which they are significantly extended, while the mark in bar 76 was additionally moved closer to the R.H. part, which does not stem from the A notation. In the remaining editions the marks were placed more or less between the parts of both hands, while in FE their range was standardised. We do not reproduce these differences – irrelevant for determining Chopin's intention – in our transcriptions.
