Yes, the Hoagies' IQ test score equivalency chart pre-dates the WISC-V.

At the bottom of the Hoagies' webpage, there is a feedback form. The feedback form also provides a contact e-mail address for the Hoagies' webmaster.

Using the communication method most convenient for you, feel free to contact Hoagies' to inquire whether information is available to possibly update that webpage to include the WISC-V in the equivalency chart.
