Well, yes. I had the chance to befriend with 2 Chads before and here is what happened.
The first one was a GigaChad-tier: one of the tallest, strongest, very knowledge oriented at that time and martial arts expert. The friendship with this Chad made me more knowledgeable and more fit, better in some of his martial arts. So, from a 2.5/10 I became a 4.5/10 one. Later he got many girlfriends. During that period I got only one. But those other 2/10s, 3/10s and even the 5/10s around us didn't get any girlfriends, I mean they became real incels during that period. One of them is still an incel I think, another one is divorced, third one somehow got married (probably betabuxx marriage case; i guess)...
The second one was just a Chad-tier: comparatively tall, one of the strongest, comparatively knowledgeable, doing one single martial art and playing music. The friendship with him made me also more knowledgeable than before, more skillful than before, more art-maxxed and kept fit. At that period he couldn't get a girlfriend (because he had a bad minn- problem which was a light mental disorder), only once he had a kiss with one from another town. Me, even being shorter, weaker, less handsome, got 2 serious girlfriends during this period and a short relationship.
So, believe it or not, the maxxing works well and you, even an incel or a nearcel, may get some chadness and be at least a bit chadish if you do all those useful actions and having the good habits.
