Hi David, The definition of "Significant animation" currently is: "Animation which continues for more than 1 second, and affects more than 1/3 of the view of the webpage." So if we changed the test procedure we would need to change the definition. Does that help? Yes, it is a big requirement. I Nat has been conducting more research. https://twitter.com/nattarnoff/status/803963858859814912 I'll ask if he has results of that survey. Thank you.
