In the version prepared for print, as well as in ACh, Chopin did not mark the scale of the final crescendo. However, such markings are present in AB and CGS and in FED. In the main text we suggest (in a variant form – in brackets) the 
written by Chopin in FED, since it is the only addition to the text of A (→FE) coming directly from the composer. According to us, the authenticity of the 
indication of CGS also seems to be highly likely, which is a consequence of a long, close acquaintance between the copyist and Chopin.
