the diameter of that circle will always be bigger than your measurement from blade to blade because of the arch in the circle. Does this have something to do with your measurements coming short?
Yes, I just took the widest point from blade to blade. Perhaps thats not right because it does leave out the third blade. Don't really matter to me on this particular broadhead though(Rky Mtn. Turbos).....I just bought 11 of these heads with an additional 15 extra brand new blades from a guy who likes to try new heads each year, at a rock bottom price.
