Same as in the middle section of the Etude, one can see here more distinctive differences in dynamic indications. In the main text we give the version of GC (→GE):
- we adopt this copy as base source;
- it is difficult to point here to a mechanism of a possible copyist's mistake;
- it is most complex, as far as the graphics is concerned – it includes three reasonably juxtaposed elements.
The authenticity of the versions of the remaining sources also seems to be probable, whereby the only significant difference concerns bar 64, in which instead of 
present in GC, FE and EE have a diminuendo (written differently).
