Cant figure out this "out of tune GT"

[Wateroksnmud]

I have an '09 70# GT, 28.5" Draw, shooting a 400 grain arrow. It has, if I remember correctly, 9 grains on the string ( a small dloop and a metapeep ). Timing is syncd'd but I do not recall which dots, maybe between 2 and 3. What do you expect my speeds to look like?

Here is a calculater. Enter your info its pretty close. http://www.bucklemke.com/ke/ke.php

I have links to like 20 calcs. Nothing adds up. According to the calc you linked me I'm at 72.2lbs of KE and IBO is 87.8.

Anyone want to earn some cash to tune my bow? I played and played, and spent numerous hours on the phone with Tater. Maybe i'm just bow stupid.

I just ran your bow through the calc Maybee listed above at 345 IBO 68 lbs 28.5 dl 400 g arrow 9 g on string and got 306 fps 83.19 ke

If you need a tuner might ask Maybee he would be hard to beat.

I wouldn't be using 345fps. , I'd use the lower end. Maybe around 336-340ish. for a calculator.
IBO's in the factory are done with an unfletched arrow(no drag) and there will be some variation with the chrono's.
And yep, I'd send it to Rick. He's top notch and knows his **it.

290 to 305

Mine is 28 1/2" with 390grn arrow. 280fps at 61lbs.

Mine is on third dot.
