I know it's been mentioned that you should use the same tape measure from start to finish because there are variances in these things.
I must mention that there are variances in angle gauges also. I have an old metal one and a newer plastic one...and at 6.5deg, they differ by about 1/2 deg. Then, I used both to check a 6.5deg setting on my miter saw, and neither matched, even though my fence was squared to the table and zero.
I guess the Chinese make measuring tools like they make their dog food.
