Each displayed time is rounded independently to the nearest second. The finish uses the exact target.
Your target and its pace
A 3:45:00 finish over 42.195 km corresponds to 5:20/km or 8:35/mi when shown to the nearest second. This page uses an even pace: equal distances receive equal shares of the original target time.
The complete target is 3:45:00, with halfway at 1:52:30. The cumulative table keeps its precision internally and rounds each displayed checkpoint independently, which avoids adding a small rounding error over 42 kilometre rows.

Check the cumulative splits
The cumulative split table includes each whole kilometre, halfway if it is a separate marker, and one exact finish. These values are elapsed time since the start. Changing the display unit relabels those same checkpoints; it does not move them to whole-mile markers.
Read the final segment
The last whole-kilometre checkpoint before the finish is 42 km at 3:43:58. The remaining 195 m takes 0:01:02 when rounded separately. Adjacent displayed values can differ by one second from a separately rounded segment; the original target is not adjusted to hide that effect.
Edit the plan or make a band
Open this target in the split calculator to change the marker interval or display unit. In the pace-band maker, choose A4 or Letter, a band size and a short label. Preview all strips and check the finish before exporting. The preset starts at an even allocation; any two-half change should be an explicit choice.
