I am always seeking out Lonely caches and figured the PGC Lonely Caches page would help me locate some near me. And it did, as GC735A1 (#7, currently) on the list has a Loneliness factor of 4471.
So I took a look at it with the idea of going to find it. But wait a minute, this cache isn't lonely, it was Published on 04/07/2017. What the...?
As soon as I looked a bit closer however, I immediately saw the problem. For reasons unknown, the Hidden Date is given as 05/04/2006 and, for reasons equally unknown, PGC is using the Hidden Date instead of the Publish date to calculate its Loneliness
Now I realize that caches published before 2005 do not have a Publish date, and the Hidden on date is the only one that can be used. However, if a cache does indeed have a Publish Date, in support of accuracy, that is the date that should be used.
Incorrect metrics are useless metrics, and given my understanding that PGC was founded to calculate all sorts of metrics and statistics, it's difficult to understand why Hidden date continues to be used in cases in which Published Date is available. I would suggest PGC take an action to correct this type of discrepancy globally.
