The missing staccato dots in bar 162 in GE1 (→FE→EE) are certainly an oversight of the engraver of GE1 (cf. bars 156-160). Similarly, the absence of dots in bar 164 in A is also to be regarded as an oversight – in this bar, the last on the page, Chopin overlooked all articulation markings in the L.H. (dots and slurs). Dots were added in GE1 (→FE→EE); however, they were added also in the previous bar (163), which, as it seems, was not compliant with Chopin's intentions (cf. bar 161 and the note on slurs in bar 159). However, this does not exclude Chopin's participation in the proofreading, since the composer could have changed the concept of markings. According to us, it is a mistake at the time of performing the proofreading or an editorial revision that are more likely.
