The missing 
mark may correspond to the notation of [A] or even to Chopin's intention – such situations are very frequent in his pieces; what is more, they do not always result from inadvertence. However, in this case the notation may be misleading – a single 
mark in such a harmonic, dynamic and pianistic context most probably means that the pedal should be held until the very end of the passage, which we specify in the main text with the help of a [] mark. However, the addition of a relevant mark in GE proves that not everyone considered such pedalling natural or even correct.
