That's the former forum member I was talking about at post #2. Quite extensive testing actually, but sadly gone. It was a sticky thread IIRC.

This is a great video. For film I always use hypo clear and wash 5 to 10 minutes with archival film washer @ 20°C. Absolutely the currently available hardening fixers make for increased wash times. Without any hypo clear., Kodak, in my old darkroom dataguide, recommended 20 to 30 minutes wash @ 68°F/20°C, important to maintain temperature, at 55°F you can wash film for 2 hours it will still be inadequate.
Excellent video!
