Differentiation in the manner of representation of staccato may stem from the ambiguous notation of the base texts and arbitrary editorial revisions in this respect. Chopin's wedges were much more often ignored by the editors and changed into dots; therefore, their presence in FE and EE may be a proof of the accurate notation of the lost manuscripts. It is very likely that the repetition of the wedge in the L.H. in EE is the engraver's error, introduced by analogy of rhythmic figures of both hands in that bar.
