BQM "Score"

If I d/l a csv or xml file for a BQM, there's a data item at the end of each line titled "Score", which seems to be "1" unless there have been some lost packets, eg (for csv file):

"Timestamp","Sent Polls","Lost Polls","Rejected Polls","Min Latency (ns)","Ave Latency (ns)","Max Latency (ns)","Score"
.

"2025-05-19 12:01:40","100","0","0","6155000","6589000","7023000","1"
"2025-05-19 12:03:20","100","8","0","6109000","32070000","1193000000","301"
"2025-05-19 12:05:00","100","0","0","6212000","6616000","7045000","1"

"2025-05-19 15:13:20","100","1","0","6205000","6629000","7246000","201"
"2025-05-19 15:15:00","100","0","0","6105000","6651000","7358000","1"

I assume it means something useful or it wouldn't be there, but I can't work/find out what.

Anyone?

I saw that and was also wondering, seems to be somehow linked to the number of 'Lost Polls'

So far I've only seen 1, 201 and 301 like your example.
