colored link on new timing chain..?

would have taken a pic, but its buttoned up now, it was a blued link on a silver chain. Usually you put it over the dot on the cam cog at about 2:00 and then count links to the crank dot. Just a more accurate way to set them up. My Mazda chain had the same procedure, but it was 3X as long. I should have reported where it ended up with the dots lined up but I didnt have the blue link over any dot.
