b. 412
In the main text we preserve the unambiguous notation of the rhythm of A. Moving a semiquaver outside the last quaver of the triplet in the bottom voice is an arbitrary action characteristic of GE (→FE→EE). The Breitkopf & Härtel publishing house would consistently apply a "mathematical" layout to such groups, denying the currency of the convention used by Chopin even in these places where the notation resulting from such a layout (as the discussed one) was absurd from the pianistic point of view, cf. the Nocturne in C minor, op. 27 no. 1, bars 5-13.
