There is no pedalling in the previous sources. While preparing the Etude for print, Chopin most probably would add indications in three Stichvorlage manuscripts, which is directly proven by GC (the signs are written with Chopin's hand), and indirectly also by CDP, probably reflecting the state of [A] before the last retouch and additions. Hence, the earlier pedal release in FE cannot be considered a mistake, as analogous bars 24 and 55 are marked in the same way. In the main text, we give the possibly later notation of GC (→GE) and EE – cf. bar 24.
