As a proponent of high FOC, my response, ironically, is a resounding “Yes’ you have plenty.
High FOC has opened a few more doors and has permitted those, including myself, who like to tinker to incur some benefit from our labor. Establishing some sort of minimum may taint the pool and invalidate most all set-ups which successfully provided food in the past millenniums.
Tiny heads, often times less width than the end of your index finger have been found over many parts of the North America. The points have been identified as ‘Bird Points’, since earlier speculation was that Native Americans used them specifically for harvesting birds. Researchers have found blood on some of these points and they were identified as deer, deer-sized animals and up to and including elk.
Your current set-up is most likely far…far superior to those of the early Native Americans and exceeds many used today.
Tuned arrow, Sharp BH and a decent mark will do well per your current set-up.
