Are you saying that the Park Chain Checker is more accurate than using a ruler? I ask, only because my chain had over 4000 miles on it, and according to the chain checker, it was over .75, but not quite to 1.0, indicative (at least to me I thought) that the chain was nearing replacement time. I took it to the LBS (good friends - they wouldn't sell me anything that I didn't need), and the head wrench took out his ruler, measured the chain, and announced that I had lots of wear left on it. It made me wonder why I bought the Park tool at the time.
