It's part of a Giant marketing video that has been circulating for quite a while. Just Google it. As for the 250g I agree it is stupid and for that reason never referred to that in my comparison. I specifically based my comparison on a 158g post. You will have to search really hard to beat that post weight.
You don't have any factual bases for your doubts about the correctness of those published numbers. Come back when you do.
