I really do get the idea of using some of these descriptions rather than standard units and "the stretched-out cat" is actually a good one, if you ever owned a cat. It would have made more sense during the Covid-19 Lockdowns if they had told you to stand the distance of a 'stretched out cat' away rather than the use of the short statured man that I saw used.
However, when you use large multiples of the "thing", it defeats the whole object of using it. If someone told me something was 980 'stretched-out cats' away that means nothing to me. And everyone probably knows the area of a Football pitch or the approximate height of a standard double decker bus, but they have no idea how large 980 Football pitches are or how high 980 double decker buses are.
The reserve will grow to the size of nearly 980 football pitches when work finishes in 10 years.
