6.1.4 Loss of accuracy for relative movements
When linking together relative movements, a loss of accuracy may occur if the final speed is not set to zero.
The following graphic illustrates the reason.

1: Sampling before

position
2: Sampling after
arriving the
target position
The current position is sampled once per millisecond. It is possible that the target position is reached
between two samples. If the final speed is not equal to zero, then, after the target position is reached,
the sample is used as an offset as the basis for the subsequent movement. As a result, the subsequent
movement may go somewhat farther than expected.
