The pedal markings of FE (→EE) in b. 142 and 144, whose authenticity cannot be denied, were most probably entered by Chopin into the basis for FE. It is indicated by the trace of correction visible in analogous b. 162 where the 
sign was moved one beat earlier in print – its initial misplacement was probably due to misinterpretation of the manuscript.
In the main text we place the second 
sign analogously to the first. In FE it is clearly printed too far.
Similarly complemented pedalling can also be seen in FE (→EE) in bars 201-204 and 221-223.
