Top three things to fix
Review the rule documentation for 'pathway_unreachable_location' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Pathway unreachable location (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
Re-generate shape_dist_traveled on export so stop and shape distances use the same units.
On some trips the stop distances run a little past the end of the route line. The stop and shape distance values don't quite line up, so any math that uses them can drift.
Effort: Usually an export-tool fix, not hand editing.
Check the flagged stop times for transposed minutes.
Some scheduled trips move faster between stops than a transit vehicle can. Usually a typo'd stop time; riders get arrival times no transit vehicle can meet.
Effort: A few minutes per flagged trip.
