IBO is 316.

Subtract 40 fps (aprox. 10 fps per inch under 30) for your draw length and you start off at 276 fps with a 350 grain arrow.

Subtract 6 fps for your peep and you are at about 270 fps.

Calculate and subtract the speed loss of your arrow weighing more than 350 grains and you are at about 235 fps.

Subtract 15 fps (3 fps per pound of draw weight) for your 65 pound draw weight instead of the IBO 70 and you are right where you should be.
