If I were to use the "Rule of 15s" which if I understand it correctly, is to use the horizontal distance, I would miss spectacularly. Even if I were to use the diagonal distance, I would be 1/4 of a mildot out and that might result in a miss. At steeper angles I expect the situation to become worse.
No, the rule of 15s means you use the actual distance. Brian said "shoot it as if horizontal" by which he means ignore the difference in height and use what your scope told you (if rangefinding in FT or bracketing).
