Never heard that name for it before, but it's perfect. Did you come up with that?

Yes, assuming the cables and routing are fine, if you are getting a click but no shift, it's probably a tension issue. And although the adjuster can sometimes take up enough to compensate, you might not have enough to play with in order to dial out any noise/rubbing. Better to undo the anchor bolt, pull firmly on the cable to get it nice and taught, and start again.
As for still ending up in the largest cog after 9 clicks, you will probably have jumped two gears with a subsequent click after having missed one.
