In A the accent over a
3 is clearly longer than the next ones. According to us, it is an inaccuracy, since there is no reason to differentiate between accents in such homogeneous texture (a short accent is also over the L.H. minim chord in this place). GE reproduced it as a short accent. The absence of the mark in FE (→EE) could be explained by an oversight by the copyist or by the engraver, yet further differences in the type and number of accents between A and FE suggest that Chopin was adding these marks independently to A and to [FC] or while proofreading FE. However, even under such circumstances, the missing accent seems to be an oversight.
