Hey Gums, see the graph in reference below at page 112.

At the bottom of page, the flight law switched from normal to direct = "intuitively" alternate law + landing gear extended, between 15:45:15 to 15:45:40. See the purple and green curves are proportional, however the elevator is at 75% (12.5 deg out of of 17 deg) for stick at full ND.
Note: Interesting for pitch in alternate law, the stick to elevator relationship, is opposite ?!
As per FCOM, the pitch in direct law is a direct stick-to-elevator relationship (elevator deflection is proportional to stick deflection). However, maximum elevator deflection varies as a function of CG. No protections are available.
