Stu calculator and I

[PERUN]

Maybe I have a problem and maybe not. That's why I ask you to write your opinions.
Stu calculator and I do not agree


take a look at
     


I am satisfied with the flight arrow

I would be happy to hear what you think

I NEVER match stu's calculator unless I put in a personal form factor of around -10.  I just tuned some new arrows - bare shafted perfectly and the only way it works on his calculator is with a form factor of -10.  I have great arrow flight even with bare shafts out to 30 yds.  Use Stu's calculator to get close and then fine tune yourself.

I use Stu's for a new bow and arrow setup always. I have found that Stu's always puts me in the ball park. Stu's along with bare shaft tuning has worked very well for me.

Stu's is pretty accurate for me.  I also find, though, that either carbons have a "sweet spot" that shows up about 8-10 lbs underspined or they are WAY more tolerant of being underspined than Stu gives them credit for.
I can't prove it, but i've seen it happen enough to believe in it.
In the end, though, go with what works for you.

x2. I love Stu's calculator. It is a great tool. My carbons consistently show 10# weak, but no biggie....i just work with it and tinker in the yard to get things perfect

in any case i am satisfied with this setup .I think is FOC good and no worries about penetration , so .....
thanks guys

I have to go to -15 on the PFF. If I leave that -15 in there all the time, then when I use the calculator for a new bow, it usually comes out real close. Never exact, but usually very close, with only minor tweaking needed.

Just because you are getting good arrow flight at 27 metres does not mean you are getting good flight at 7 metres or less...that is the real test

It's almost always dead on for me.
