Such differences, sometimes significant, in the notation of pedal release can be found in Chopin's pieces a few times, mainly in the context of dissonant melodic elements overlapping the dying sound of the bass note, e.g. in the Barcarolle, Op. 60, bar 115 or in the Prelude in C
minor, Op. 45, bars 5-6 and analog. On the basis thereof, one could assume that Chopin meant gradual pedal release, the so-called diminuendo pedal, in the case of which it is impossible to define the exact moment the pedal should be released (in other similar situations Chopin did not put a 
mark after a 
mark at all, e.g. in the Nocturne in F minor, Op. 48 No. 2, bars 112-114). Taking into account the above, in the main text we give both source marks, regarding them not as an alternative, but as extreme possibilities between which one can look for one's own sonically satisfying solution.
