The 
mark in b. 91 is the only pedalling marking in AI. The four-bar pedal in the later sources develops and specifies it, although the placement of the 
mark is unclear due to the differences between the sources. According to us, in this context the individual sources are rather a result of inaccuracies of notation than of different concepts. In the main text we take into account the message conveyed by the mark written by Chopin in AF – before the 1st note of b. 93, i.e. at the end of b. 92. At the same time, it is a graphical compromise between the notation of AF and FE & GE1 (coincidentally, it corresponds to the notation of GE2).
