F2A category- I’m Canadian citizen

Timeline:

I-130 - 09/25
I-485 - 12/25
1st RFE - 12/25
Biometrics - 12/25
Interview - 02/26
RFE after interview 03/26 and I-130 got approved same day.
FTA1 in March 2026 2 weeks after RFE submission

Api updates:
I got silent updates every month on 1st and recently got on 14 aug twice and FTA1.
Got silent updates twice yesterday and got approval today.

I was just wondering if there’s a pattern or reason why some of applicants get their interview schedule and Rfe done within few months of filing while some applicants have to wait for interview notice or rfe’s when Final action date becomes current.
