I knew that he wasn't updated yet and this I thought was a seperate issue to
the case in point?

There is also a new WIDEn-N digi North of Knoxville, in North Anderson

Actually, if WA4KJH-7 actually supported Wn-N, you would see the KF4OWQ-2
London, KY digi, because when in the Cumberland gap, I could hear both fine
and I could bounce via both of them when using a capatible path (WIDE1-1,TN
on the London side, and TN,WIDE2-1 on the TN side).  It's good to hear about
the new sites.

This depends on what the network is trying to do.  If you design it to cover
50 watt mobiles, there are too many in the area, but it you are designing it
for HT style coverage you would want more.  That's why I was interested in
the receiver site digi project so when a 50 watt mobile rolls through an HT
coverage area, they get one W1 hop rather than 3 or 4 of them.  My work on
this area is stalled because APRSD just won't stop crashing in this
configuration.
