Fluctuations in the return chamber create fluctuations in how the pump operates , this then leads to fluctuations in the overflow , the gatevalve is set based on the pumps running condition so any fluctuations on how it operates is derectly linked to your herbie oveflow , It is very common in herbie set ups

Throttling back the pump won't do anything as its not the speed of the pump but the consistency it's running at.
