i don't think this Sanji and Zoro "AP" comparison is precise in anyway...
sanji draws less blood breaks more bones
Zoro draws more blood breaks less bones
that's a sense of a technical kicker like sanji and a swordsman like Zoro

Unless your bones are broken in a fatal area, like your neck or your skull, you are likely to survive. But if you got slashed, even if in places considered less vital like arms or legs, a cut deep enough carries a serious risk of blood loss and therefore of death.
That panel reiterates that Zoro is more lethal than Cook, and that's okay.
