Have you found that to be true all the time? When I first got the program I was doing something with the program that would change the spine slider but forgot what it was. I stopped using it for a while and then I sent an email tothe guy who made it and he told me thatthe performance slideronly if you want to change your set-up for a particular arrow. So, that confused me about if I was doing it right so I stopped using the slider. If that makes any sense at all? That's when I started having the issues with the program spining the same way it used to for me.

Your last sentence mayexplain an issue I was running in to. I would change it on the equipment set-up tab and noticed that I couldn't reach an IBO low enough for my bow.Some things just are not explained out well enough evenby the guy who wrote the program.

Thanks for the info. I'll try it out.
