In the main text we give the slur of FE (→EE), since the vast majority of subsequent slurs, present in a similar context, is led to the 1st quaver in the next bar in A – out of 13 slurs in b. 1-12 and 15, it is only the slurs in b. 1, 8 and 10 that end on the 6th quaver; two (in b. 6 and 9) are ambiguous. We consider all the above slurs to be inaccurate, since the differences in the range of slurs are not related to the structure of motifs, e.g. the shorter slurs in b. 1 and 8 are opposed by the longer ones in similar figures in b. 2 and 7. Moreover, in A one can see corrections – the slurs in b. 4-5 and 5-6 were being extended (in b. 3-4 probably too). Along with the crossed-out staccato dot at the beginning of b. 2, it may indicate that the concept of markings of those figures changed from  to . Consequently, the aforementioned shorter slurs would be uncorrected elements of the initial slurring.
The slur beginning from the 1st quaver is an inaccuracy of Fontana, repeated in the next three bars too.

The  asterisk under the last quaver in the bar is probably Chopin's mistake. In the next bar a  mark, entered into A also under the last quaver, was later crossed out and put under the 3rd quaver, as it is in all the remaining bars of this progression (b. 33-35 and 38).
According to us, Chopin probably wanted to introduce longer pedals for them to correspond with the advancing crescendo; however, he eventually gave up this idea and left the mark in the discussed bar by inadvertence.
