I can successively add one to the other. And sooner or later they will go wrong. In order for them to go smoothly, I need to put the first one perfectly even. It’s practically impossible.

I will try to explain very simply. Choose two far-growing thin trees on the plain at a distance of about 15 foundations, connect them with an imaginary line and try to put foundations between them along this line so that they do not deviate from it, and so that both the first and last touch the trees. You simply cannot do it.
