I did a video comparison against a K band speed sign to see how much of a difference TSR made against constant on (we all know it makes IO suffer badly).
I was actually pretty surprised. With TSR on, you get barely any reaction time. Granted, this was around a corner with a concrete barrier, but I have see LEOs sit here before.
Sorry for the shaky camera... I was using my iPhone on a cheap window mount.

There was a 9 second difference between alerts! Approx. ~860 ft of extra slow-down time.
This is actually a bit scary. I thought TSR was only supposed to mute the alert for a second or two?
