I've put in my set up and it says stiff by .015 (it says it.s .415, and my spine is a .400 spine).

How bad is this? It seems like it's not that bad, if I add half an inch to my arrows it puts it perfect.

I'm not striving for perfection, but how close do you all want your spine to be to the target spine? Stiff by .015 looks good to me, I'd rather be a little stiff than a little weak.

Thanks
