Brooks saddles as a natural variable product, vary. My guess, when you sit the saddle sags.
otherwise the declination should cause you to slide forward.
you might check the tension- too limber and the saddle will splay and wear out faster. Too tight will not help either.
nice bike.
Literally brand new B17. And I weight 150 pounds, so cannot imagine there is much sag. I used to have a Specialized Romin on it, which was great as well (the Fizik Arionne was a different story, Hated that saddle).
