when you pop branch, pick up 1 orb. Then pick up another. Then wait 7 seconds after that, and pick up the third (This is what "1/1/7" means when people mention it). Is the "Optimal" way, however to see the output impact of various other pickup times, can see this sim: https://www.raidbots.com/simbot/report/nDmsMZ5ZxoMBXGLHfcpeLC
Ultimate takeaway is that 1/1/6->1/1/9 are all basically the same, and other pickup times aren't too far behind, as long as you pick up the first two orbs relatively early.
