Cancellation phase steps can jump up or down by 360 degrees at level minima

Evidence

In these cases, the dependence of the cancellation phase on the lower primary level follows a curve that is almost 360 0 lower that expected. This means that the phase pattern depends on the individual or on the parameters, and can produce phase jumps downwards at the levels of L1 for which the cancellation level reaches a minimum, or phase jumps upwards in order to reach a similar value but 3600 higher. — Professor Dr.-Ing.
