I put all 8 lines into 4 separate containers to test the flow initially and to make sure they were feeding the same on every line. But since the plants aren't going to uptake at the same rate, one plant is going to run off before the others. So, instead, you have to feed until the thirstiest plants get good runoff.
So then, take the Liters per minute from the live testing (not the pump's rating) and divide that by 5 for 20% runoff.. Then throw those numbers away mate. Just make sure the big girl is running off decently.
As an example, when I first transplant, I'm watering for about 45 seconds. Towards heavy stretch/early flower, it's closer to 1:30. I've been doing 2 per day but that seems to require dropping your EC a bit else they start to tip burn.
Setting the timer is easy enough and the pump has plenty of power for a .8m lift. (Lift pump is what I've always called them btw)
Clear as mud?

edit to say there is also a circulation pump, a tiny one, in the res. It's always on.
