As far as testing the sanctuary rank feature, this is used by the SanctuaryQuorum to determine your sanctuaries place in being called into service to process and vote on the filtered magnitude files.
Only do this if you are a synced sanctuary with a position in "masternode winners" report. If you are not in winners, this command will be useless as we only choose sancs who have a rank.
If you have a place in the payment queue type 'exec testranks'. The tail end of this command shows the sanc count, and it looks like we have a piddly 4. Anyway this means you should see (since we need a minimum of 2 voting sancs in testnet, 10% in prod with a minimum of 5 in prod), an alternating 50% chance of being called to filter or vote on a file, for every Other block number (since 2 minimum divided by 4 is a 50-50 chance per block). So now look at your heights starting with the current height and go forward in the future - IE right now we are on block 10005 so go from 10005 to say 10025, and just see the pattern, is it 0%, 100%, 0%, 100%,100%, etc. If so our rank is working.
I am looking at my testranks report on my hot sanc and it appears this is working. (The number is height, percentage of being called, and Sanctuary Rank) in the report.
