The notation of accidentals is incomplete in the majority of the sources. However, these are patent inaccuracies, typical of Chopin, and FE1 oversights, equally unambiguous:
- in A there is no
before the bottom note of the L.H. chord on the 2nd beat of the bar (B) and no 
restoring b
on the 4th beat; - in GE1 only the former was added, while in GE2 – both;
- FE1 is missing both accidentals overlooked in A; in addition, there is no before the final L.H. semiquaver (c1); FE2 added only a to b;
- EE has the correct notation.
