At the beginning of the bar A (→GE→FE→EE) does not have the 8 digit, marking the bottom note of the octave, E1. Since at the first appearance of this phrase in bar 14 Chopin added it in A, it is highly likely that the addition could be applied also here: omitting one (or more) of repeating places at the time of proofreading would often happen to Chopin in various works. It is worth remembering that, writing the Concerto in Warsaw, Chopin did not have the E1 sound at his disposal, since the scale of his piano reached to F1 only. Cf. bar 82 and 89.
