MP40 child mode

[Yanir34]

Hello , I have 4 MP40's in my SPS tank.
I want to run 1 pump as Main pump , and that the other 3 will work synchronize with it.
I know that there is "Child Mode" that copying the operation modes from the main pump but here is the tricky question:

During the day the main pump is working at several different modes , at different % .

How can I activate the other 3 pumps that will work exactly the same % in power ?

for example if the main pump is working at 75% at "Reef Crest" mode , how much % should I activate "child mode" - 75% or 100% ?
Hope you guys understand me

The child pumps should be set at 100%. That means it will operate at whatever you set the primary pump to but at opposite times so when one is ramping up the child is ramping down...etc...

I think you can only have one child per primary though but not positive.
