Just goes to show you, no matter how retentive you are there's always someone else more so. Yeah, I measure all kinds of stuff especially when I was deciding which TT frameset to get. I compared the P3, Siice and 8 different Chinese models side-by-side. For my bikes I record in a notebook I keep on my bike stand all the fit measurements. Great park document and it's "cute" how they use a board to get a straight line. I use two laser levels mounted on tri-pods. GL
