I never said "a few days", I said a week. Don't know where you got "a few days" from.
You can describe one week as a few days too. If you wanna be specific then be it. Calling it a week won't change anything though.
Not a few days. A whole arse week. That is a long time for recovery by One Piece standards.
So by your own admission Lucci is an admittedly inferior Zoan but a Zoan nonetheless.
So you are saying that the recovery time is comparative to the level of zoan devil fruit (i.e. regular, ancient or mythical) against damage dealt to said user?
Well comparatively, Lucci got pummeled way harder than Queen and King did in their respective fights and had an inferior fruit on top of that and still recovered in a timeframe that you previously labelled as "several days".
A week is a long time for any standards but that doesn't make it a magic number that makes all kinds of wounds disappear. There is no rule that suggests no wound in OP is allowed to stay after one week, so there is little logic in suggesting all wounds disappeared because one week passed.
Queen and King were dealt enough damage to render them unconscious. Lucci was mercilessly pummeled by Luffy even after he lost consciousness and then some.
So weaker user with an inferior fruit that was comparatively more injured recovered in "several days" i.e. less than a week.
It's true Lucci took quite some damage for his standard but King and Queen are eating attacks that are several tiers above the ones Lucci ate. They too ate more than they can chew. King, in particular, took damage that is way beyond his level. His condition is even worse than Kaido's against Oden, so it makes sense for someone this weak to take a long time to recover from that kind of damage.
1) Good thing the Beast Pirates have Queen, also one of the best doctors in the world who used to roll with Judge and Vegapunk.
Queen is a scientist, not a doctor. Although I won't deny he likely has medical experience, his expertise lies in making weapons while Chopper and co excel at curing people. He's nowhere near as good as Chopper as a doctor.
2) Gifted bodies that recover from damage? What you mean like Luffy the Zoan or Sanji the Medical Experiment from Queen's former work colleague?
Like Zoro who took worse damage than Luffy and recovered at about the same time as him? And Kid and Law, who took more damage than modified human Sanji and recovered as quickly as him.
