The slurs in b. 2 and 6 (as well as in b. 18) explicitly encompass already the grace notes introducing the trills. In this situation, we consider the slur in b. 10 to be inaccurate; in the main text we suggest a slur analogous to the remaining ones. The notation of FC is vague – three out of four slurs run rather from the 2nd grace note (only in b. 6 from the first one). As such a notation is musically unjustified, we assume that the copyist meant slurs starting from the 1st grace note in all places, which is how it was interpreted in GE.
As far as the end point of the slurs is concerned, according to us, the notation of A in b. 6 and 10 points rather to boldly written slurs (which were obvious to Chopin) than tenuto-slurs led to the end of the bar (see, however, b. 18).
