In the sources bars 160 - 163 are slurred differently. The FE (-IE) variant and EE may result from the imprecise notation of FC3.
The GE must be a free interpretation, and yet here we also find differences - in the first three impressions there are only two slurs on the two beats of b. 161. Only in GE4 a slur on the second beat of b. 160 and a slur on bars 162-163 were added.
