Short accents in A (probable interpretation→GE)

Long accents in A, possible interpretation 

No marks in FE

Vertical accents in EE

The accents in A are shorter than the ones over the bass notes in this bar, but the difference is so insignificant that it is uncertain which marks Chopin meant here. The absence of marks in both impressions of FE is either an oversight or a revision – the latter seems more likely, especially in the case of FESB, which was based on GE2, during the final period of its presence on the market, hence when the plates must have already been as worn out as evidenced by the copy presented in our system. Upon seeing the very clear outlines of the removed elements, they could have assumed that the accents over d1 were the remaining elements of the initial, misplaced marks and that it is only the accents over the bass notes that should stay. Anyways, a possible change introduced by Chopin while proofreading FE1 seems less likely than one of the above possibilities. 
The change of the accents over d1 to vertical ones was a typical arbitrary decision of EE.
