EK3_MAX_FLOW with H-Flow

Hi guys, I’m using the H-Flow for Non-GPS flight. I noticed that we have this parameter, EK3_MAX_FLOW with default value is 2rad/s.

In the H-Flow specs, they said this Optical Flow can up to 7.4rad/s.

Should I change the parameter follow to the specs when maximum value just 4.0rad/s? Will it give me a better brake when I give a fast move on quad?

which flight controller are you using?
