I'm not sure about this statement. It sounds reasonable but I can't recall seeing any research about FID being a proxy for all input delay throughout the entire duration of a session. I would hypothesize that optimizations that improve FID would also tend to improve input delay in general. My main message here is just that I haven't seen that research.
