I can’t find a reference to that but China did 17 minutes in January this year. I think you’re confusing the announcement that they increased power by 17x while maintaining plasma.
This test was 20 minutes at a higher power setting without being incredibly destructive, that’s their milestone.

Yes but 22 minutes is longer than 17 minutes
Think of it like a pizza oven
How well done is your pizza?
