It's silly not to provide all the evidence available, when I-751 instructions say:
"Submit copies of as many documents as you can to establish this fact, to demonstrate the circumstances of the relationship from the date of the marriage to the present date;"
I wouldn't necessarily say it's silly to include all pages or only enough to satisfy the evidence as requested, it's open to interpretation. I feel 3 monthly accounts were sufficient, if they RFE me for more they can have that too. I just don't think that's likely with the other evidence I have provided.
