What should change

Worked out from this month’s eligible provider predictions and ranked by the sample they affect. Each line says what the feed evidence shows, when, and which operator can review it.

The diagnosis for this month has not been published yet. It is produced once, when the month closes, because it re-reads the eligible provider predictions for the month.

Not covered here

• Whether scheduled trips actually ran. Provider predictions do not establish trip delivery; that requires separate evidence.
• Whether eligible provider predictions imply even or bunched spacing on frequent routes. Measured over a recent rolling window, which cannot be reconstructed for this closed month.

Prediction sample, but not enough of the month

These routes had eligible provider predictions on fewer than half the days with prediction evidence this month. Those predictions count toward the network figure above, but the routes stay out of the rankings because their sample covers only part of the month.
