"-- Ophis, at  less than 1/4 of her full power ,--"

* This quote refers to immediately after Cao Cao and George stole Ophis' power. She felt "weak", but was still more than twice as strong as the Heavenly Dragons.

"--Ophis sent most of her power to another space in the form of snakes while being caught by Samael,  which she later retrieved.--"

* This means that, after the events of vol.11 & 12, she got back most of her power, making her around 3/4 her full power now.

Since Lilith has 1/4 Ophis power, that means Ophis is currently 3/4 her full power. And if less than 1/4 is more than 2x stronger than Heavenly Dragons, than that makes her more than 6x stronger than Heavenly Dragons in her current state.
