Oh, Lord. He sets up a "book" template to reproduce the effect of typesetting on his manuscript, so it doesn't seem to take as long to produce his page count. This is so many kinds of wrong it's hard to know where to start.
Professional editors care about
word count. They take your word count and plug it into their own formula, which varies from house to house, to come up with "their" page count. That is part of the production process.
The production process is no part of the writer's job. The writer's job is to
produce a manuscript, and most editors prefer a standard page with 1.5 inch margins, double spaced, with a half-inch paragraph indent in an easy to read font like Courier 12.
That is the only "template" you need.Futzing around with formats and fonts and what have you is a colossal timewaster for writers.
