The military one isn't the best but like you said its repeatable, I was always over weight but under tape in the army. It is a good way to gauge your self and for cutting weight when you are trying to build muscle so you can make sure your not loseing muscle also.
Did arms this morning and I feel like a beast, like stretching those sleeves haha. May go join a gym today so I can progress more. Lots of stuff I want to do I can't do at home.
