Yes, single port. I haven't seen any dual here in Switzerland. We have mostly ROW versions.

It seems logical to me, that it will retard on boost:

At Idle it is almost 0, high depressure over spring tension

Then with increasing rpm the spring gains against the falling depressure

As soon you're on boost, the spring ends to the max retard position (Not the centrifugal advance)
