On the 4th quaver of the bar in JC, there is a figure which fills a crotchet with its rhythmic values: 
. According to us, the error consists in writing two-time bigger rhythmic values and could be already in [AI]. This kind of mistakes was frequent in Chopin's works, e.g., in the Nocturne in D
major, Op. 27 No. 2, bar 56. The hypothesis allows to explain also the creation of the version of EF: having encountered the error in [AI], Fontana corrected it with the method of as little changes as possible, extending the lower beam. In the main text we give the probably unique authentic rhythm, recreated faultlessly in PE.
