Pretending that one phrase or sentence is completely unrelated to the rest of the paragraph, pretending that you can't tell whether 3.6 is the open loop gain unless I say it is, and in spite of the fact that the last sentence in the paragraph says this is completely overridden my the closed loop components is intentionally disingenuous. I am interested in answering the question of the original poster (See post #1). "I'm trying to understand the gain of each of the two stages."That's incidental to the mistakes of both conjectures, and it's not telling us much.
Your math shows exactly the gain of the two stages, and you want to argue against it???
