Question about resetting achievements and impact on Steam Replay / AGCR

Hi everyone, I’m someone who really cares about achievements and completion order. Recently, I realized that in one of my games I unlocked some achievements out of order (a mission triggered before another one), and this really bothers me. To fix this, I found out that it’s possible to reset specific achievements using a Steam console command. Before I try it, I’d like to understand the possible consequences.

• If I reset and then re-unlock those achievements, will everything look as if nothing happened?

• Specifically, does this affect Steam Replay (end-of-year summary) or the AGCR (Average Game Completion Rate)?

• Or could it create anomalies, like incorrect stats, broken records, or strange behavior in the profile?

I’d appreciate hearing from anyone who has experience with this, or knows how Steam tracks achievements in the background.

Thanks in advance!
