The notation of the accidentals is inaccurate in some of the sources, although it does not create any problems in interpreting Chopin's intention. However, describing the inaccuracies is impeded due to the different graphical layout of AI and A (→FE→EE), in which first six semiquavers in the L.H. written in the treble clef (from the 4th semiquaver in bar 32) are placed on the upper stave. As a result, the 
before g1 is unnecessary in these sources in bar 32, yet it has to be repeated before the 2nd semiquaver in bar 33. In AI there are no naturals before G and g2 in bar 32 and before g1 at the beginning of bar 33, while before g2 on the 6th semiquaver in bar 33, there is a cautionary . In A (→FE→EE2→EE3) there is no before g2 in the L.H. (in bar 33).
