Cheats
Well they showed how it actually works in Bowfinger. The studio looks at page 1, page 7, and the last page. And that last page had better be page 118.
It's not quite that bad. But scripts are expected to come in at about 118 pages. Page 2 Stage solves this problem in a very simple manner. You tell Page 2 Stage how long you want the script to be and Page 2 Stage reduces or enlarges the script to fit that length.

A Better Approach
Page 2 Stage uses what is generally considered the best method to handle cheats. The entire script is reduced very slightly in size (on the order of 0.1%) which allows each line to be a little longer and fit a few more lines on each page.
The beauty of this approach is that the script looks totally normal to the reader. All the margins are correct. The text all looks correct. It's only if the reader holds a page from the script over a page from another script that they will notice that the letters appear to be just a tad smaller and the lines a tad closer together.

The Magic
So how well does this work? Beautifully. For up to 10% either way, it's very hard to see the difference. Yet that change will decrease or increase the script by approximately the same percentage.
This is not magic. You cannot cut the length of a script in half. But nothing will make a 236 page work in 118 pages. It just can't be done.
And equally important, the Page 2 Stage approach takes almost no effort from you. You tell it the number of pages and the program finds the smallest change that matches that length. And it keeps that multiplier when you save and change the script so the cheat stays.
You can also set the multiplier yourself if you prefer.

Why this is important
You don't have to change a number of settings to try and get a page length, just tell the program and it will fix it for you.
