You do realize that nockdown power is myth, both in archery and gun hunting. Neither devolope enough energy to actually nock an animal down, or kill it by sheer shock.
When looking at energy figures keep an eye on momentum as well KE. Both play a role in penatration, as well as many other factors. Like tuning and head choice.

Paul is right.
I think most people get KE and knock down power confused. Or have a vague understanding of it.
