There are no grounds to question the authenticity of pedal releasing marks in FE (in b. 509), or in GC (→GE) in b. 510. However, the EE pedalling - a separate pedal mark per one chord in b. 510 - seems substantively very doubtful, as in most cases Chopin marked the necessity of adding the sound of notes played in different time. We believe the basis for EE may have had two 
marks by mistake and the engraver or editor while trying to make sense out of this notation, added 
. In the main text we present our variant proposal that includes two undoubtedly authentic versions of pedalling.
