The interpretation of the three 
marks in A can be approached from different angles:
- Literal interpretation, in which the range of the marks is related to the respective R.H. crotchets, which results in three increasingly shorter marks. Such a version, suggesting increasingly shorter and milder crescendos, matches the descending direction of this sequence;
- the difference in the range of the first two marks may be regarded as insubstantial, which suggests that all three hairpins should be unified, since the shape of the melody is the same in each bar. We suggest this version in the main text.
The versions of the editions resulted from the marks in b. 170-171 having been unified; none of these changes resembles Chopinesque proofreading process.
