In b. 21, 24 and 27 Chopin provides the R.H. figures with two "triplet" slurs in A (→FC→GE1), most probably to emphasize the return of the principal rhythmic scheme after the groups of bars featuring quintuplets. It is unclear whether the whole-bar slurs of FE (reproduced in EE as 5-semiquaver slurs) result from the engraver's distraction or whether they were changed intentionally (to make one's work easier?). Five-semiquaver slurs were also introduced in GE2, which was a logical consequence of standardization of the R.H. rhythm in the entire Prelude.
