kata => 1.1-1.2 (he is probably as strong if not stronger than king but king don't care about honor and fair fight also have some race related ability and is a ancient zoan defeating him is way harder than kata and queen in top of ancient zoan is a cyborg and had dangerous weapons)
smoothie she is trash she first need to learn how to cut a wooden door than how be to be somewhat useful
cracker he isn't strong enough he would became and f6 ( i don't think kaido would accept some one with trash endurance in all stars that are monstrs in endurance and durability
perospero => 800-900m he is fairly strong is very smart and has very good endurance (he get nuked pointed blanked and was still active with heavy injury in wci) he probably would get fairly high rank because of it also combination of peros and queen would be pretty dangerous (a dude that can make any thing from candy he build a huge factory for ceasar and a crazy scientist specialized in making cyborgs and crazy weapons)
Not only these two facts, but also the issue of calamities being much more active and recognized for their violence (they even gained the fame of Drought, Plague and Incendiario because of it) than their BMP counterparts. We will have a better answer for this by observing how the fights will be: Inu Vs Jack in parallel with Peros Vs Neko.
Depending on this result, we will know if Jack's 30% more reward compared to Peros is honest with his strength level or if he was inflated by his infamous acts.
is it fair?
jack inu and neco are injured
jack was fighting whole army of sulong minks then he fought sulong neko and inu and get f ed up and inu and neko f ed up by kaido
pros also fought carot an wanda but expect his injured face his fine
we have f ed up jack (dude get f ed up pretty hard in roof) vs f ed up inu and f ed up neko vs perospero with some injure
also bmp are also very violente they destroyed 3 island and killed thousands of people just for 1 tea party if you check dialogue of people it seems that for every tea party they will do some thing like that.
they also destroyed 1 country in FMI if you check dialogue of people it
most of beast pirates activitys is in wano each of them is in charge of one state of wano jack was in charge of kuri and queen was in charge of udon we now that jack will do is in charge of business relates stuff queen is in charge of prison mine
it's just an assumption that Beast pirates are more active in outside word we don't have that much of the fact to support it the only examples are jack going to zou after samurai (wano related stuff) and king and kaido want to go to marine ford
honestly why the fuck we don't now any thing about king?
