Good stuff. I would go further even.

When I write such a document, I first bang it out without editing, and then I go back and ruthlessly remove anything that I can possibly remove.

"Probably"? "Perhaps"? "As I said above"? "On the other hand"? Gone. There are probably 120 other such phrases.

Details? Probably not necessary, gone. If someone thinks to ask, I have the answer.

Talking about alternatives? As little as possible. Cut, cut, cut until only the most essential part is there.

So I cut it down until it's quite rude in its bluntness.

Then I go back and warm it up. "Thanks to the good work we already have on this project." "We have previously exhibited success in these areas." Chatty, but now I have made space for a little filler in the first step, so I can do this, and it heartens the audience and makes them proud.

Then I look very very very hard at the first and last paragraphs and try to make them as strong and as clear as possible.

I remember once reading an essay entitled, "Why I am selling this vessel into the nuclear test zone." Decades later I still use this as an example of an elegant punch in the jaw, without wasting any words.

And voila.
