What can ZPF Theory achieve in terms of Cosmology?

Can anyone please tell me how the calculated results from the link below
might be wrong (if at all)? .... It relates to the Hubble Constant & CMBR
Temperature.

I'd like someone to tell me, not just that they're wrong if they are, but
why they're wrong & how it is that the approach achieves such precise
experimentally validated results.
