Trying to understand why brconnect is analyzing the same table partitions every day?

In checking my analyze log, I have noticed that brconnect is collecting stats on the same table partitions every day. 

I just want to know why this is happening as these partitions should not be changing.

I would also like to get an understanding of what the numbers represent at the end of the "BR0883I" lines below.
I am running the command: brconnect -u / -c -f stats -t all -p 4  which is running BRCONNECT 7.20 (25) on Oracle Enterprise Edition 11.2.0.3.0 

Analyze is not collecting stats on the rest of the partitions every day (this is the normal behaviour that I would expect).
