Are my C's regenerative brakes "touchier" than typical brakes?

I'm trying to get a discount on my car insurance from Liberty Mutual, so I recently agreed to plug in (under the dash of my 2012 Prius c) a little device from their RightTrack program. It tracks my driving behavior for 90 days.
One of the criteria is how much "hard braking" I do, i.e., the "number of occurrences of rapidly decreasing your speed."
I'm only 8 days into the program (though I haven't driven every day), having driven 165 miles, and I'm already judged as having 2 hard-braking "events":

first (on Feb. 9): from 23.0 to 14.3 Mph (duration: 1.0 second);
second (on Feb. 14): from 14.3 to 6.8 Mph (duration: 1.0 second).

I don't have a 2nd car, so I can't compare vehicles, but It seems that my brakes "grab" a little stronger than I would normally expect, so that I'm not really "playing on a level field" with other cars.
I feel like writing Liberty Mutual's CEO, suggesting they consult an unbiased, expert organization (such as Consumer Reports' auto-testing centerI about this issue, but first I'd like to hear from some regen-brake experts in this forum.

 

Yes, Mendel, I drive quite conservatively, always staying in Eco Mode to maximize MPG. It's always good to be reminded to keep a "decent following distance," as "tailgating" causes any driver angst as they look in their rearview mirror.
