Yup, I must fess up. That's exactly what I did! I'm in bad need of a vacation. However, I did check my scales at the lower end (15 Lbs) and it is on. Have not checked it around the 70# range yet. I will say, when turned all the way up, the bowfeels every bit of 77# when I draw it. It's all I can do to pull it. I supposesince everything else is on I will not worry about it. I shot it at60 # and it's fine.
