In A the pedalling of these bars, seemingly inconsistent and differing from analog. b. 2-4, could be considered inaccurate, e.g. due to having been written in haste. However, it turns out that if we take into account the R.H. part, the pedalling markings fall almost exactly in the same place as the first time. It seems highly unlikely that it could have been an accident; therefore, Chopin apparently marked pedal changes in this vibrating dominant ninth chord to separate the sections with minor ninth (b
1) from the sections with major ninth (b1). This is how we interpret it in the main text. In the remaining sources, the 
marks were rather adjusted to the L.H. notes; moreover, GE arbitrarily moved the last change of pedal to the beginning of b. 20.
