Score the rack typical then non-typical. IMO, it is definitely non-typical. Non-typical antlers are 1st scored as a typical, differences noted on score sheet. Abnormal tines are then measured and added to the score. For a typical score, abnormal tines are subtracted. Hardest part of scoring a non-typical is deciding what is normal/abnormal. Unless you plan on entering it in "the book", measure it yourself and subtract nothing. Gross score best ID's the animal, nets are for fish.
