At the beginning of b. 79, in FCI we can see a d2 crotchet combined with a tie to a d2 note in the previous bar, while the R.H. part is written down with the use of two-part notation already in this bar. A d2 crotchet is also at the beginning of b. 81, yet there is no d1, 1st bottom voice quaver.

In As, in which the second half of this section (bars 81-96) is written only in the form of alternative versions of the first one (bars 65-80), the bar is to be interpreted as identical to bar 65 (except for the bass note at the beginning). However, it cannot be excluded that it is an inaccuracy of notation and that Chopin provided there for a version with an agrace note, like it is in AI.
The slurring is discussed in the adjacent note.

Both forms of the rhythm are undoubtedly authentic and both are justified by certain stylistic arguments. In the main text we give the probably later version of PE.
