It would have to be a heck of an 8pt though to score 136. This deer is going to have to have a 17 inch spread, bases that are close to 5 inches and then hold it's mass pretty well, and it's going to have to have main beam that are in the 23 inch range inorder to score 136. That's not a bad method but the deer has to have a lot more going for it than just the tine length for it to work. I would imaging the formula would work better for a ten than it would an since you also have the additional circumfrence measurement to take up some of the slack it may lose in other areas. I don't think it would be the method for a new hunter to use when money was on the line. JMO Someone with a little more experience could use it very effectively as a tool for judging because you would also be able to take into consideration mass, spread, and main beam length, again JMO.
