One of the sources who'll be reviewing my treatment is a studio exec that happens to be a friend of mine, so I know she'll make an exception and at least read it.
You have such a great opportunity here - a friend who is a studio exec who
is willing to read your treatment. A friend will read it and then you can ask
questions.
The reason you see contradictions is because there are different "treatments"
for different purposes. You say you want to send this treatment to agencies
and studios; what do you want from agencies and studios? They do different
things so your treatments will be different.
Do you want an agent to rep you based on this one script?
Do you want the studio to read your finished script?
Do you want the studio to pay you to write the script?
Do you have a completed "package" to pitch?
Each will requite a different type of "treatment". So ask your friend who is
a studio exec what she wants to see. Then take this amazing opportunity
to sit down with her and work out your pitch.
