Flaps extended: 10° pitch, N1 between 70 and 80 %
I wouldn't have thought that would be helpful in the landing config, given the normal pitch attitude is 0-1° and 60-70% N1 on the 777 and that's on a descending 3° glidepath. I haven't tried it out to see what happens but from inspection you'd get rather slow fairly quickly.
This seems to be taking "one size fits all" to extremes. Like rvblyky7 says, better to know a few more likely pitch/power settings or use what was working before the airspeed became unreliable.
