All of your proof is counterproof for 3 refined.

One sale at 3 refined probably isn't going to be enough.

Also I don't wanna be that guy, but that 3 refined sale was level 42, and that could entice collectors to go for it. I'm not saying it's a big deal, but the possibility is there. Especially since there's still sellers for 2.33 on the market still.

I've sold these hats for 2.33

While there was a 3 ref sale, there are plenty available for 2.33. After 5 days of mostly unsuccessful and no additional proof, it's a safe downvote from me.
