So even if he doesn't scale In skill to Valvet he still is super skilled and a great planer
I think you’re missing my point here, I'm not meaning to deny Jaune might or might not be a better strategist (because he most probably is). What I’m saying is that this definition of Skill comes out as rather simplistic on how skill or intelligence in general works. But let’s go for it.
Jaune also on numerous occasions been able to form plans on the fly to work according to the advantages of his team and counter possible threats, including several threats that were significantly strongr than himslf and his team as individuals
The premise on it's own is a valid shown of intelligence and skill. However, here is when degrees come to play. Prior knowledge, settling and abilities at disposal are all important traits to keep at mind. This isn’t Jaune leading a team, this is Jaune fighting on his own straight against someone who he knows nothing about and viceversa. He
might make his mind to outsmart Carapace, he
might not need it, Carapace
might defeat him sooner, or so on.

Ok. But how does this measurement of skill works?
I know that Carapace is about as skilled as, let say, Anansi, because Anansi is not only physically superior and Carapace hold his own against her, but also because Anansi has traits that play way on her favor such as gaining an hyper mobility, flexibility and two extra sets of arms longer than Carapace’s body length that makes her martial arts more dangerous and competent than they would normally be.
Carapace doing this might attests that he's good at physical confrontation, but this doesn’t makes him a kickboxer or even less a better kickboxer than Anansi, nor it means that he would be as tactically smart as her if she were to make a plan that involves conquering the world. So a need context about this skill.

I think pointing what's going on here after saying what I said before is redundant, but there’s this important thing to say: similar to how skill can make up for AP, AP can make for the lack of skill. Saying fought is an ambiguous term when there’s a lot of things that come to play in fight. Is as if I bring the argument that Queen Bee is implied to be the worst temporal miraculous holder yet she still managed to effortlessly best Stormy Weather, who went from controlling weather to control all the forces of nature to the point that
she could move the earth out of its orbit due the
experience of being akumatized previously for a couple hours.
And so on
