Dumb question but do you measure the distance from the balance point of the arrow and divide the distance forward of the balance point by the distance behind the balance point to get the percentage? (Damn I hope all of that makes sense to somebody)

In the link you will notice that it gives the reason why you select FOC and it does not say anywhere in there "So I have a male arrow that will break through bones."It is used to fine tune an arrow for long range target competitions.Notice though the chart of different FOC's that are commonly used.
There is nothing wrong with being over the 15% but being under 10%may cause instability in a broadhead. As I stated previously there are benefits to having the weight forward on a hunting shaft. Especially if you are not shooting a high speed bowor or a newer high draw weight bow that can not produce a large amount of momentum/penetration/KEwith a 5-6 GPP arrow. I actually believe that if you shoot a slower bow you should use as much FOC as you can to ensure that as much force as possible is not lost on impact. It seems a lot of people that I talk to outside of HNI are around 12% to 13% that have 60to 70 lb draw weight bows.

RE: weight of broadhead
There are multiple ways to accomplish the end result, but the most important thing to pay attention to is your FOC. Keep it at a minimum of 12% to 15% for broadheads.
I have some FMJ's that I built with 100 grain brass inserts to achieve over 20% FOC with a Slick Trick 125 grain mag. The extreme FOC arrows really perform awesome!

RE: weight of broadhead
Having a high FOC with the weight forward hasa slight advantage because most of the weightis on the most solid part of the arrow that upon impact the force will not be misdirected by the flex of the arrow.
I concur
