The stem prolonging the g quaver was overlooked both in FE (→EE1) and GE). Chopin added it in FED and FES; moreover, in both copies he also prolonged the last a quaver. We consider that addition, most probably introduced independently in each of the copies, a development of the original idea and adopt it to the main text.
It remains a mystery how the reviser of EE2 found out about those prolonged notes.

In the main text we mark the use of "harmonic legato" in the L.H. part, as Chopin did in b. 3. The first a note was also prolonged in EE2.

As was the case with b. 4 and 79, we keep Chopin's authentic notation as almost certainly intended by the composer.

EE1 has wrong key signatures in bars 28-49 – 6 sharps on the upper staff in bars 28-49 (4 lines of text), and 5 sharps on the lower staff in bars 28-43 (3 lines). This astonishing mistake was corrected in EE2. Interestingly, the additional sharps change the pitch of only three notes in this entire fragment – e1 to e1 in the middle of bar 38, and at the beginning of bars 40 and 41.

As in many other places, Fontana replaced the Chopinesque grace note with a common short grace note (the change also got to EE2, probably via GE1). In the main text we keep the notation of A (→FE→EE1), although it most probably carries the same meaning as a .
