The direct referral to rule 33.1  (in contrast with citing) did not confuse me by itself but that was combined with how much it is probable to use the common paper size than that other size which sounded as something the court allows because of being considerate to litigants with some strange document fetish.

That in addition to how ,except for the article/post below which I found afterword, I did not notice any complaint by others. 

I learned from the link in the previous post that you can higher a professional service for that. My main problem with such arrangement, however, is that the hedge fund guy would immediately contact and take to his side those running that service just like he does everywhere around me.
