What was your other question? I already answered your first one, even if a High 1-A is normally comparable to a tier 0, they could still never actually reach tier 0 since that means they once had a weakness. A Tier 0 never has any weaknesses ever, so if they at one point had a weakness then they aren't tier 0.
