I am not gonna downvote you but you will need to find your manners. People around and most certainly your colleagues will be grateful for that. Perhaps also learn to deal with the arguments and different opinions without coloring them "plain wrong" in advance. Give people around you the benefit of a doubt.

Maybe it's because it is not off? It's not terribly difficult to sum up all the matmul calculcations and number of bytes one needs to load and store per each layer in self-attention. My number could be off for a bit but it is certainly not terribly off.
