Again, the quote that states it's not possible in the first place is weird, since Fenrir at 80% should already be above mid god-class and the time stop still worked, when that quote supposedly says that the time stop doesn't work on gods. Therefore, I see no reason to believe the time stop won't work on Ddraig when the form is completed and both Rias and Gasper become stronger. After all, they both still have plenty of growth left. Also, it was never said that stamina is the only flaw it has, or that the power of the form will not increase.

Whether it works for 1 second or less is, once again, irrelevant, because it can be done repeatedly, especially when stamina problems are solved and power increase from perfecting it is taken into account.
