@ Looigi, I'm using a 6in digital caliper with the chain mounted on the bike and under tension, measuring the upper run. Keeping the caliper's ends aligned against the pins just seems to come easier for me than using a ruler.

It does sound a bit too good to be true right? still, it lines up quite perfectly at 6.000in on the new chain, and on the old one too until a couple weeks ago. Over the past two months I tested it countless times and always got the same results, so it's consistent as well.

Cool, thank you. I was planning to get a third chain too, do you think that would be overkill?
FTR, the cassette is a SRAM PG-1070, and the cheapest price I can get a new one for, is ~2-2.5x that of a mid-to-high range KMC chain ...with sales those are usually less expensive than entry level models - go figure.
(BTW thanks for your many useful posts, I'm a bit of a lurker here and your contributions are always a very interesting read)
