You forget that humans can match namek LP.
In POB most of fighters used 20 con/50 resistance x2 rings and full con armor and props earrings and CON Dogi, matching base SK HP, since SK use %LP,%lp,con armors and mostly everything else props.
Like I said, it not only it would help chef, it would help its party and I am sad to see that you are still stuck in "Korin Platform" set of mind, where people do not even give af about it. It is there to have fun when you are bored, nothing more.
