One of the nice features of D3planner is that it shows the "percentage of perfection" of an item; that is, how close to the absolute best possible roll for an affix the item has, expressed as a percentage.
For a PoE example, an iLvl 77 1H Axe (Flaring) can roll +phys damage od 20-27 to 41-49; 0% would be "20-41", 100% would be "27-49"; basically, how close to the maximum average damage is this affix within the tier.
Some things are trivial, such as "of Nourishment", which is fixed at +5 life on hit, so they would always be 100%. (Alternately: ignored in percentage calculations entirely. Either one works.)
It also shows the "overall" perfection: the average of the individual affix and implicit "perfection" percentages, so that something with an 80% +phys, and a 20% +light, would score an overall 50% on the perfection scale.
It's clearly not a substitute for actual judgment about the item: a low overall perfection score might still be way better for me than a higher overall perfection item that had lower scores on the things I cared about; if that concerns you, just presenting this additional data for each affix would certainly make it easier to see how good compared to possible this is.
