In the sources the  returning dis missing both before the last demisemiquaver and the next two notes at that pitch. Chopin's oversight is undeniable, yet if we were to evaluate the sound only, one can ponder whether the  was supposed to be already before the last demisemiquaver or only before the dotted quaver in the middle of the bar. From the psychological point of view, the second possibility is much more likely: it is hard to assume that Chopin would have forgotten an accidental differentiating two adjacent notes in a chromatic passage.

In the 2nd half of the bar, both the absence of the first two staccato dots in GE (→FEEE) and an additional dot over the demisemiquaver in EE is certainly a result of an inaccurate work of the engravers.

In the editions the last note is written as a hemidemisemiquaver. Therefore, the group filling the 4th beat of the bar contains a fractional number of demisemiquavers – 8½ in GE1 and 9½ in FE (→EE), which must be regarded as a mistake. The engraver of GE1 probably shortened the last note, kind of "automatically" – cf. bar 41. The mistake was revised only in GE2, by reducing the value of the rest, which does not correspond to Chopin's original intention expressed in A. However, it could be that an additional beam was added in GE1 (→FEEE) upon inspiration from Chopin, whereas leaving the rest without any changes was merely an oversight. In that situation, the version of GE2 would be a rational correction of an inaccurately performed proofreading of GE1. Such a possibility would be indicated by the overlooked '9' digit, determining the number of demisemiquavers in the group. The above analysis of the rhythm of the roulade's ending is binding regardless of the versions of its earlier part – see the previous note in this bar.
