What I "used" to do back in the day was hammer a finishing nail in the wall.
A nail small enough (narrower than a link pin) so chains would fit over it.

The first chain was unused, it would mount flush against the wall-unstretched. It was never used. It was a control chain. It would dangle to a certain length.
Subsequent chains were mounted outboard of it in order of useage, the longest chains being the most stretched. They were rotated, using the shortest chain (compared to the unused shortest chain) first.

This worked well, until I moved, forgot the order, and 13 years later, I have my retirement savings tied up in jumbled campy chains in a drawer in my garage!!! Arghh!!!

I will never retire now!!!!
