No, he isn't, and neither was I. The Divine Presence has not been mentioned as a part of the discussion. I've already made this assertion, and the argument is not based on the Tier 0 profile in any way.
Perpetua is also inferior the GEB, which is why UDM can't scale above it.
I'm not basing this argument from that profile, and I've never mentioned the Divine Presence.
You have, again, fundamentally misunderstood the problem. No one is saying beating Perpetua is necessary for a character to be 1-A, but rather being 1-A would place UDM above Perpetua, which he is not. Therefore, scaling UDM above the GEB breaks the cosmology.
