From your explanation, I still don't understand what you did. If you're saying you used "see" every time you paraphrased and [no signal] when you directly quoted, then you probably did an OK job. The line between "see" and [no signal] is very gray when you are paraphrasing. BB says you use no signal when the source "directly states" the proposition. But if you're paraphrasing facts, usually that will not need a signal. If using "see" when paraphrasing facts was your worst mistake, then I wouldn't discount your paper very much.
