does not make it clearer. It’s a paper, not a lecture to undergrads.
I may kill myself if I have to review another paper in which each section goes: I am going to do XX. XX. I just did XX. And a long winded introduction listing AA, BB, …, XX and a conclusion restating AA, BB, …,XX.
I don’t think that the extra pages improve the chances that I will understand the paper. They just bore me. I am smart enough to figure it out — if you explain it clearly, one time.
