In A, Chopin marked correctly only the first out of three notes requiring an accidental in both passages – b in bar 474 and c
3 in bar 475. All necessary signs were added already in GE (→Fe→EE). Moreover, a cautionary 
was added before f1 at the beginning of bar 474. In the main text, we also add a cautionary before g2 in bar 475.
