Image Permanence Test -- Status?

On pg 50 of the book “Way Beyond Monochrome,” in which the authors discuss a 4-print image permanence test, the book references results at the then-current 10-year mark, which was 2010.

Is anyone aware of a way to see the most current results of this test? Is it posted somewhere? I've googled (including here) but cannot find anything.

I can't comment on the WBM tests. Maybe Ralph Lambrecht can.

If you are interested in image permanence - well, there is an institute just for that: https://www.imagepermanenceinstitute.org/

Thanks for that link. I wasn’t aware of that group.
