Adjustment of Status - I-485

Hi guys, my PD for concurrent I-485 application is Oct 7, and I'd finally had my biometrics done 30th Jan. My current case status is 'Fingerprints were taken'. I was curious about how the cases before and after me had been doing, so I found a GitHub script which I ran to check the status for 500 cases (250 before and 250 after my case number). The PD of these cases seem to be between Oct 7 - Oct 16. But here is what I found:
