A1 is devoid of dynamic hairpins and accents in b. 5-18, which is a result of the working nature of this autograph. To the main text we adopt a mark that was an attempt to reconstruct [A2] on the basis of its two representations in CJ and CK. However, the interpretation of both is subject to some uncertainty due to the use of abridged notation of the L.H. part and in CJ also due to the lack of synchronisation in the notation of the parts of both hands. Consequently, the versions of both copies, and even the interpretation of CK given in CB, may be considered a potentially accurate interpretation of Chopin's intention. The absence of the mark in EL is probably a mistake.
