NM/SH's neighbour, SW, probably did hear noises but not necessarily on those dates. SH and NM were at Crown Hill on 19th Feb between 11am and 2pm so that part cannot be correct.
Question is, is SW more sure that the noises were on consecutive days or is she more sure she can tie a particular noise to a definite date?
The argument could have been on the 18th – a possible trigger for the assault on Becky the next day or it could have been on the 19th as a result of the aftermath of Becky’s death.
The moving of heavy objects could have been on the 19th when NM was alone in CML or it could have been on the 20th when both NM and SH were at CML.
I don’t think the prosecution is assuming SW is a day out - it is in his interest to suggest she is.
