The key hither is nix balances. Having a gravid mention bound and not victimization (maxing them out) shows that you live how to use cite.
If your aggregate pipeline of reference is 5,000 on one lineup and you use it to the max apiece month, but pay it off apiece month, hurts you since you are victimisation 100% of your usable cite.
