Hi Chris,
 
Unfortunately I don't have the logs, only the high watermark value in the dashboard. I have disabled logging in Winsock as bad spots were never an issue for me (I think the bad guys know that CC Cluster does rate limiting).
 

The picture shows that I rate limit non-RBN spots as follows: 1/overall number of spots to 500 per minute, 2/spots per each DX to 25, and 3/spots per spotter to 10 per minute. These numbers assume a busy contest weekend.
 
I also started paying attention to the number of spots that are older than 5 minutes:


During ARRL SSB that number exceeded 500,000 and of course they were all dropped.
 
Perhaps we could partner in another area- help me finish the code I shared. It is a cluster for clusters, a switchboard of sorts, that rate limits spots for all connected clusters. As I mentioned before I am not a developer; my developer experience is dated and based on ADA, C, and Pascal, no Perl. Specifically, I can appreciate help fully deconstructing the partner handshake and enabling clusters to connect to the switchboard cluster.

Rudy,
Would you be willing to share the debug log of that event (80,000 sp/min), if you still have it? I wouldn't mind trying to see if there is any info to pull out.

Let’s think this thru:
 
1/Logs show spots with H as high as 98! Recording the node of each hop will increase PC61 payload on average 6 characters per hop. Let’s say average H is 50, that would be 300 characters plus the delimiters or about 350 characters.
2/My cluster received over 80K spots per minute. Imagine the traffic created by 80K messages with additional 350 characters per PC61 message.
 
Can you describe the full algorithm you are proposing? How are you going to use the additional data to make a decision to accept or drop a spot?
 
When comparing PC61 to BGP remember that BGP is designed to support two-way data flows. PC61 is strictly one-way and doesn’t need routing overhead.

Mike, this is why I'm saying that we need to record the whole path, not only the last hop.
Every node has to append it's ID.

The current release does tag spots from the incoming node partner with a 
"via" tag. You would need to analyze all the logs in between, using the 
"via" tag to trace it back to the source.

THAT was the equation. EXISTENCE!... SURVIVAL... must cancel out... 
programming!
