In A bar 505 is the last one on the page and the slurs in this and the next bar do not fit together – the slur in bar 505, although it does not go beyond the bar line, suggests continuation, whereas in bar 506 a new slur clearly begins. In this situation, the version of GE is most probably a result of Chopin's proofreading, since it seems to be unthinkable that the engraver of GE1 would have interpreted the slurs of the base text in this way on his own initiative. This conclusion is confirmed by the traces of corrections of this slur in print, visible in bar 504, cluster of the slur with the 
mark in bar 506 and an earlier ending of the slur in FE, perhaps corresponding to the slur of GE1 prior to the final proofreading. The ending of the slur of EE reaching the beginning of bar 506 seems to be inaccurate, yet it can be a result of a revision.
