Why does the relative axis of the map not always quite follow the yellow time limit line?

Below we see that the black y-axis of the map is slightly to the right of the vertical yellow line. This is because the software searches about 1 millisecond to the right of the yellow time limit line to find the maximum and it then moves the picture to this maximum. This is because the y-axis of the “early reflections”-picture should line up directly on the maximum level as shown in the picture below and not before the maximum level.
