Timestamp mismatch

There is a discrepancy between the intro skip timestamp on Infuse and the timestamp uploaded on Theintrodb website. What are the reasons for this inconsistency? For example, Episode 4 of 低智商犯罪(low IQ crime) The intro timestamp on Theintrodb is 2:59 to 4:25, while on Infuse it shows 3:11 to 4:21.

Infuse uses both introdb.app and theintrodb.org for timestamp data, so depending on the title it may be pulling timestamps from one or the other.

This TV drama has no information on introdb.app.

Infuse can also pull markers from the media server (Emby, Jellyfin, and Plex) and would prefer these markers over those fetched from either of the online databases.
