I think you better research the tables again because Rossweisse is the fourth biggest among the girls, and she is way bigger than Xenovia and Irina combined because she is listed at 96 cm compared to the meastly 87 cm bust of Irina and Xenovia the only people that surpass Rossweisse in size are Rias and Akeno and Kuroka only.

I also know that in Japan Rossweisse is considered beyong a G cup because they base their cups by the bust using a system similar to the Europen system.

Rossweisse is the fourth biggest among all the girls, and Issei rates her very highly in all departments but the women in the series that beats them all is Gabriel according to Issei she is superior to Rias and Akeno,
