The version of As, replaced then by the final edition of those motifs, resulted from corrections itself. Their traces in the form of crossings-out are almost invisible on the available photograph; however, a comparison with similarly looking corrections in b. 18-19 suggests that in both places Chopin began with similar ideas and then changed them in a similar manner.
The change of the long grace note to a short one was an arbitrary decision of Fontana, certainly contrary to the intention of Chopin, which is particularly confirmed by the Chopinesque entry in FED, difficult to interpret as a whole, but in terms of rhythm almost certainly tantamount to the addition in b. 19, which is perfectly clear.

Initially, the 5th quaver of the bar in As was a f2, which offered a more schematic melodic sequence – counting from the beginning of b. 17, the melody consisted of 3 analogously structured four-note motifs.

In an earlier version of As, two versions of the ending of these bars – one- and two-note – were presented in reverse order. The crossings-out visible in As suggest that Chopin initially wrote there more complex figures, comprising three or even four notes. The rhythmic variants at the end of b. 19 – see the note on b. 11 and 19.
