Crude to distillate yields

This may be a silly question but I never get my crude tested because I’ve been working with my supplier for some time. We typically get a 55-60% yiled on his stuff (start with 1000gs and get 600 in return).
Someone new offered me winterized crude and showed me the lab results which was right below 63% total thc. What would be a typical return on this winterized crude be? Below 63%, at 63%, or above 63%?

Assuming that the final distillate is 85% total thc.
