I think maybe I described what she did badly. She did mark the exact measurement on the yard stick. BUT how I'm saying a little was added was that she started a little past the yard stick. Some of the bolts were really badly cut to begin with so in doing that I ended up with a smidgen extra. I'm guestimating that it was 1/2 - 1" more cause I know it wasn't exact or short.... so not a huge amount over, Just enough to make a difference :)
