In ESKD 2-105.95 ed.2005 there are paragraphs: 4.1.9; 4.1.10 talks about the correct design of indents and that it is desirable to have a title on a new page. In accordance with this, the following questions arise:
According to GOST, I have a one-and-a-half interval, if I take 3 semi-precise intervals, then I get a large empty piece of the page, is that how it should be?
If I end 1 section on half a page and start a new one, should I move the new section to a new line, taking into account the fact that the previous half of the page will remain empty?
