You've agreed with my point without realize it. TSA has a copy of your AA records (linked to PASSID) so when you fly DL (again, linked to the same PASSID) your PreCheck success rate "should" be the same. As from a risk perspective, you pose the same level of risk regardless of what airline you fly. (i.e. clean background, combined with frequent travel).
