"Every 4-2.4sec 8% missing hp"

Not completely true. The CD calc is right, but the 8% health ratio derives from MAX health, not missing. Actually it's 100+8% of the target's health, capped at 375 damage. To put it simply, Poppy's Q has 100~375 base damage, depending on the target's health (Check it ingame, the wiki article has some missing info).
