737-800 HUD had de-acceleraion rate. At touchdown, with max reverse and spoilers deployed, it was approx 2.75. Reduced to 2 at 90-100 kts while still using max reverse.
If you have auto brakes 2 selected you’ll feel the brakes engaging around 90-100 kts as the thrust reverser and spoiler drag no longer provides the de-acceleration required at autobrakes 2.
