FOC is part of a tuned arrow.
Yes but your original post made it sound like a broadhead will have a different point of impact because of of a higher foc. This should only be true if the broadhead is actually heavier.
The 1% to 2% foc increase because of broadhead length is not going to make a broadhead impact lower.100 grain on the front of the shaft is all that matters.
I actually agree with the rest of your post.
Broadheads can be tuned to the same poi but will not have the same flight characteristics as fp's.
