The area around holes / eyelets can yield to an extent before cracking - resulting in a drop in tension in addition to that caused by the load brought on to the rim as a whole when inflating a tire.

This true in particular with thin walled soft aluminum rims such as old superlight Martano's from the 70s for which the rim would start to yield at approx 50 KGF.

The thing that stands out to me in the OPs post is the 110 KGF for a 36h symmetrical front. The Kinlin rim in question is a superlight using Kinlin's alternate material that enables high strength in a thin wall. (xKeyMet catalog as opposed to their Standard catalog that uses the standard alloy. They have TWO lines of rims, not one.)
