Been my experience beam length and mass are where the numbers really can change. Also longer brows help immensely as few deer have much over 3” brows but throw some daggers out there on fat bases and you can easily pick up 5-7” over an average brow with pencil horns. Carry that mass into the second or third circumference and that’s another 3-5”. I think mass is hard to judge unless it’s just a log beamed beast. Depends on if the oval is vertical or horizontal how they look from the side.
