In the entire Var. II AsI does not contain any performance markings except a metronome tempo. Moreover, there are two options – 
= 76 (with pen, most probably earlier) and = 92 (with pencil, later), out of which none was deleted. We do not comment on the missing marks in further, detailed notes.
The shorter tempo/character indication in FE probably comes from Chopin*, who could have marked it in the basis for FE. However, as the issue is uncertain, in the main text we keep the generally synonymous marking of A (→GE→EE,FESB).
* Four years after writing this somehow pedagogical remark "ma accuratamente," Chopin could have considered it childish and certainly inappropriate. What is more, the letter in which he describes that it was only thanks to the conductor that "he was not able to play at breakneck speed" his Concerto in E minor in October 1830 allows us to assume that the real addressee of "ma accuratamente" could have been teenage Chopin himself. Therefore, it would be all the more understandable that in 1833 Chopin, conquering Paris as a pianist and composer of five works with orchestra, not to mention Nocturnes, Mazurkas, Etudes or the Trio, decided to remove this indication, evidence of his unbridled youthful temper, although it was impossible to guess its origins – if our assumptions are actually true.
