In Af the L.H. rhythmic notation is more accurate in this entire fragment that starts here (until bar 267, the last one written in Af) – every half a bar, over each bass note, there is a quaver rest filling the top voice. The absence of those rests in A and the editions is a manifestation of the budding Chopinesque economy of notation, according to which rests the sole function of which is to fill the bar in one of the voices, are worth omitting for the sake of legibility if – as is the case here – it does not disrupt the understanding of the arrangement of voices and their rhythm. Cf. the note on bars 16-17 describing a situation in which a similar procedure turned out incomprehensible and misled the engravers.
