The first one is assembling one side at least 2 meters long to see if the joints match well. Second is to assemble two sides together at least three pairs and each pair at least one meter long.
4.The tolerance of the T&G is also very important, in order to keep the chevron joint well and no height difference, most the of the manufacturers like to make the T&G too tight, that will give the installer big headache when installation, so the profile have to keep the right tolerance.
