Put two or three units on one axis and tier. Read the difference first, then the values behind it.
Ordered by PWR, Max tier, highest first
No operands are selected, so nothing is compared. PWR at each unit at its own final tier.
Nothing is selected yet. Pick a unit above, or start from the roster, then add a second one to see a difference.
Changing the units, the axis or the tier needs scripting. The comparison above is the one this link asks for, and at most 3 units are ever compared.
