I agree! The information was from a post on Flickr, the author was seeking an answer to the same question, called Clayton, and Clayton confirmed to him that the formulas were identical.

I have no basis to believe or disbelieve it, aside from Thomas' comment.

That said, the Massive Dev Chart says the time for F76+ diluted 1+19 is 7:30, which lands right in the middle of Michael's recommendation. So it seems a good starting point for testing.
