Whats wrong with using the full runway length for landing?
I have to go below glide slope to touch down at the beginning.
You canīt do that in a bigger aircraft, because you are sitting several feet above your landing gear, but in a CJ not a problem at all.
Crossing the threshold of a runway at 50 ft and fast can be seen at this picture:
