Pulsating Alternator Gauge

I feel that the pulsating ammeter is normal, here is why...
My setup:
Stock 67 dart 273, reman round back, single field wire alt with ~2.5" pulley, aftermarket voltage regulator (electronic).

There is a lag for the voltage regulator(VR) to change the control of the alt to respond to a load.

When I step on the brake there is a momentary movement to the left on the needle then it settles back to center. At idle it is more pronounced then at speed. But it is there at both.

The turn signal draws then stops drawing, the VR responds but too slowly so it bounces. Again more pronounced at idle.

Note when the brakes are on and the headlights are on the needle is slightly to the left till the rpm come up then it is centered, but even with all the load the needle still bounces when the blinker is on.

I agree that clean contacts, heavier guage wires and even a MAD bypass are all good things but if the only issue is that the ammeter bouncing when the turn signal is on I don't feel it is an issue.
