That’s why I omit it for comparing things. The more important factors are mentioned above.

If you want energy number for use on game they already exist elsewhere. How about we use them?

This is the legal minimum for the UK. This way we don't need to posture about what would be required. Just use the published minimum that surely has had extensive research done to arrive at. Say we just use 1700 ft/lbs as a minimum?
*Edit*
Or we could use the Swedish data.
Only rifles can be used for certain game, including moose, red deer and bear. For ammunition the following requirements apply.
Bullets which weigh at least 10 grams (154 grains) must have an impact energy of at least 2.000 joules at 100 metres from the muzzle. Bullets, which weigh between 9 and 10 grams (139-154 grains) must have an impact energy of at least 2.700 joules 100 metres from the muzzle. Such ammunition is classified as Class 1
2000 joules = 1475 ft/lbs
2700 joules = 2058 ft/lbs
