There is a contradiction in your statement ""Sirzechs then he was relaseing his true form was 10x the original maou"" ""at the height of Sirzechs he would be about 20x the strenght of"" this in of itself make your original statement moot as you stated yourself that Diehauser is about half Sirzechs strength ""he would be about half the power of Sirzech as Sirzechs could destroy gods."" Diehauser can't be half as strong as Sirzechs and then Sirzech being 20x stronger then Diehauser.

I think there is some confusion here. Diehauser could probably rival Sirzechs when he is in his regular form and Diehauser is at full strength, but when Sirzechs releases his true form, he is then 10x stronger then a maou. Diehauser is stated to be in Maou class, which we can assume means when he is at full strength he is comparable to a Maou at full strength. Since we have established this we can then say that Diehauser=Maou Maou*10=Sirzechs true form.

Also Diehauser's technique has been revealed to be a canceller, where he can cancel the special abilities of a devil. Although I don't know if this is for all belial, I guess we will have to wait to read the translation before confirming.
