The visible in FED deletion of the second of the grace notes indicating the beginning of the trill does not influence the performance, yet it proves that Chopin notation was incomprehensible already for some of his pupils. The notation – indicating the beginning of the trill from the bottom second 
– remains one of the most frequent reasons of misinterpretation of the Chopin text.
