The pedal markings in b. 162 and 164 were probably introduced by Chopin into the basis for FE (→EE). In the former one can see in FE traces of the 
mark having been moved a beat earlier in print, while misplacing a mark is much more likely when reproducing a manuscript than an entry in a proof copy. The first 
mark is placed in FE (→EE) after the 1st quaver in b. 163, which must be inaccurate. In the main text we standardise the pedal markings of both bars (cf. b. 142-144 and 201-204).
