Happy to see someone support this approach. I think both approaches have their valid context. If you know a lot about the negotiated value then making the first offer is great because you can anchor the bargaining. But if you don't know then it's better to wait for another offer and get yourself anchored, because your own assumptions might be way off the scale and of course if you know less about the topic than your negotiation partner then of course you need to pay a little extra at some point anyway.
