DPS and estimated total damage output (TDO) are computed against Mega Aggron's actual typing and Mega boss stats — each attacker's best fast + charged pairing, ranked by the combined DPS³ × TDO score. Legacy / Elite-TM movesets are excluded. This is per-boss matchup math, not the neutral-target tier list. Full formula on the methodology page.
