Anyone else pretty strong but suck at armwrestling?

So I can bench 3 plates. Squat 405. Stronger than average male by a lot id say. I even do arm wrestling specific lifts like cable wrist curls, reverse grip curls, bicep curls, chest supported rows. All with high intensity especially the forearm work. And I will lose to people I bench 100lbs more than who don't even do arm wrestling lifts.

Like I don't get it. I would think a year of forearm training when most guys who go to the gym don't even train it would make me leagues ahead. I even have a 80+ inch wingspan 39 inch sleeve i think, which I think is supposed to be a pretty big advantage right? I also can close a coc #2.

I feel like I just am genetically so weak at arm wrestling or I just have the world's worst technique.
