It clarifies (for discussion purposes) whether the buyer is complaining about nothing.
Asking for four or five figure offers sounds like fishing, that is, the seller is unclear as to the value they want too.
It is also circumstantial and depends on many things including the sellers mood.
They may have done lots of business and be feeling rather buoyant so will aim for 5 figures.
Alternatively business could be sluggish and a four figure offer might look an attractive option. There are sooooo many variables .
