Yesterday is the previous calendar day in Africa/Lagos. Finished matches show the score in place of the kickoff. The tip on the row is the selection that was stored, so you can compare it with the result.
A finished score does not rewrite the tip. If the selection lost, the row still shows that selection. Postponed matches stay marked as postponed.
One day is a small sample. A winning afternoon and a losing afternoon are both ordinary. Do not turn yesterday into a rate.
Use the list to review what was published, not as a stake for matches that have already ended.
