Jeff.
From my testing of arrows the programs says.
The numbers are that close it's not funny maybe a couple of grains with the actual measured weight and a few FPS with the speed.
That was out of my bows set up with loop and a Hooded Ball Peep both with and without the clarifier.
Now if I was you I would go with some extreme FOC around 24% ifn you want a hard hitting great flying arrow that has very little drift in heavy cross winds
All my arrows have the FOC up around the 22 to 24% range and that includes my 3d arrows, altho I do get called a few names on the 3d course when others have to pull my arrows
