Re-setting the stab to neutral (4 units on the 75 and 2 units on the 76) was SOP in my company prior to merger. Post merger this has been stopped. There were two reasons for the practice:-
1. during the pdi a quick check could be made to confirm stab position against indication in the cockpit (the neutral position aligns with the stab marker on the fuselage)
2. In the event that the stab position was forgotten during pre departure checks the stab was already in a fairly neutral position and therefore it was unlikely to over rotate and tail strike. (the stab position after landing is always "aircraft nose up" WRT neutral but also quite often it's still within the TO warning green band so there is no aural warning WRT a/c configuration, BUT the a/c may tend to over rotate due to the already nose up position of the stab)
My tuppence worth is that it is a potential hole in the cheese. But what do I know huh?
