First of all, I do not use any bot to archive my talkpage. I manually do all the tasks. Below is the table containing all my talkpage archives.
• Firstly, No active thread/discussion will be archived.
• Secondly, I won't keep any message older than 12 months from current date (29 July 2021 (purge)) in my talkpage.
• Third, I'll keep at least 4 threads in my talkpage. So if there's an older thread, don't think I overlooked that.
• Finally, I'll archive my talkpage within 10th-17th of each month.
Note that, these criterion follow a precedence from the first. So implementation will begin from the higher to lower one.
