I hope someone can answer this.

My bow has an IBO rating of 290fps. Now as I understand it this is at 70lbs and 30in draw, however my draw is at 32.5in. So with everything else being the same what speed would my bow be at?

I really don't care about the speed, it shoots just fine and penetrates well, I have just always wondered about how many more fps (if any) it would have at 70lb & 32.5in vs 70lb & 30in.

Thanks
