See <http://www.k3lr.com/w9zrx/AR-Cluster%20Filter%20Commands.pdf>, near the top of page 5.

Looking at those definitions: Skimvalid looks for multiple spots with the same callsign. Skimbusted looks for similar (e.g. "off-by-one") callsigns that are already marked as valid. A busted spot could still pass as Skimvalid if enough skimmers bust the call the same way, but if the correct call has already been spotted there, adding Not Skimbusted to the filter may help prevent the busted spot from showing up.

Whats the difference between, if any, between NOT SKIMBUSTED and SKIMVALID ? My skimmer filters use SKIMVALID and other than occasionally getting a T in front of some calls, they seem pretty reliable …..

For all AR clusters you can enter a filter command that takes advantage of spot quality filter: SET DX FILTER NOT SKIMBUSTED

That does a great job of eliminating bad RBN/skimmer spots, based on work by CT1BOH. Not perfect, but really big step forward.
