The stretto - - indication was almost certainly added to A after [FC] had been finished. Such an explanation for its absence in FE (→EE1) is supported by the fact that in this group of sources the next agogic indications are missing as well, that is più mosso in bar 294 and sempre più mosso in bars 306-309. The oversight of the dashes marking the scope of stretto in GE, a frequent inaccuracy in the Chopinesque editions, seems to be important in this case, since the A notation most probably indicates that stretto is to be applied only over the course of one bar and a half and not, as it could be expected, until più mosso in bar 294. In EE2 the indication was repeated after GE1.
