Yes, cutting after several days is useless other than making a
pattern. The internal shrinkage cracks are already established.

Saw joints (contraction joints) need to be cut as soon as you
can get on the concrete without raveling. Depending on
temperature and humidity conditions, you might chance waiting
to the next morning, but concrete will usually have decided
where to crack by then.

So cutting after a few day is useless?
