If you write an answer of 5 on your test, you do not get full credit.
You need to write 5 kilograms. Without units, data means nothing.
The term "no true data or analysis" (nice cherry picking on what was written) meant "incomplete information" in that sentence. It does not have to mean that the data is false, it can mean that the data is incomplete. I'm sorry that you want to be some type of literalist and pick a fight, but sorry, I don't want to fight with you today.
The OP was simply making an observation which is totally legit. The inference that can be made from the observation is that the PHB (at least) is still selling very well through Amazon - which is great for an older product facing a lot of competition.
There's not much more to it than that.
