A does not have pedal markings in bars 65-116, 197-248 & 648-707 (in the manuscripts bars 648-695 are marked in an abbreviated manner as a repetition of bars 197-244). Subsequently, Chopin added them in FC (→GE1) in bars 65-104 & 197-248, and in FE (→EE) in bars 65-116 & 697-707. In FC he did so in a more studied manner, as a rule carefully indicating one pedal for each pair of bars based on single harmony; this is testified by a few deletions of unnecessary, hastily written 
signs (see also commentary to bars 65-117 about supplements of dynamic markings). Nonetheless, Chopin did not avoid two inaccuracies: he added an unnecessary change of pedal in bars 225-226 (analogous bars 93-94 have one pedal), and omitted an indispensable change in bars 235-236. In FE the pedalling is more mechanical – only bars 65-66, 81-82, 97-98, 110-111, 113-114 & 697-698 do not have a change of pedal within a single harmony. In the main text we accept the pedalling in FC, corrected in the aforementioned places and supplemented according to FE and analogous bars. A few complements were also made in GE2 (→GE3) – the pedalling from bars 237-248 was copied to analogous bars 105-116.
