Well after 12 years of more data taken. We can finally start showing the data. The 12 penetration factors are up dated.

There are some common sense things in there such as statements on broadhead sharpness. There are some things in there which are quantifiable such as arrow weigh, momentum and such. There are things in there I agree with. There are things in there that are just not completely accurate. There are things in there I disagree with.
I'm not an Ashby worshiper though.

What parts are not completely accurate to you. I will let him know your thoughts next month when I go see him.
This is just the beginning of the data. There is a **** ton of data remember it’s been 12 years of more collected data

He called me and I have no doubt he is a lot smarter fellow than I am
He called me after I made a post in Trad Gang about needing a 1200 grain arrow that would spine out of my 84# bow.
I built exactly what he suggested and it worked very well.
I was somewhat surprised he did not recommend his own broadhead.

I had the same arrow get different result at similar distances on similarly sized animals.
If the science were so exact I wouldn't blow through both sides of a 200lb boars shield with one shot then only get 10" of penetration on the next one.
Yes, some of the math works. And if you are the only man on earth hunting an elephant with a recurve or one of the few doing the same on Cape buffalo it probably will help you. But out of the millions of other bowhunters it is over thinking the equation. If not the tens of thousands of deer and pigseach year killed with mechanical broadheads on the front of arrows at 7.5gpp and 11%foc would still be alive because nobody would get enough penetration.
