In A, the third and fourth chords in the R.H. contain patent mistakes: there is no accidental before the third one, which results in a f
2 simultaneously with f3, whereas before the fourth one Chopin wrote a 
before the lowest note and a 
lowering e3 to e
3, which also results in a f2 simultaneously with f3. The sharp before the 4th chord, unnecessary in the current configuration, confirms the assumption resulting from a comparison with analogous bar 110 that Chopin meant f2-f3 in the third chord and f2-f3 in the fourth one. This version, without errors, is present in FE2 (→FE3), corrected by Chopin. In all sources based directly on A, the following inauthentic corrections were performed:
- in GC, the copyist added a necessary before the topmost note of the 4th chord (f3) while omitting the before e3. In GE, the text was revised to the correct version of FE2;
- in FE1, the before the lowest note of the 4th chord was omitted, which, however, did not influence the correctness of the notation, which still contained two mistakes;
- in EE, a was added before the top note of the 3rd chord, which resulted in a harmonically reasonable version, yet certainly inauthentic in the face of the Chopinesque proofreading of FE2.
