Just compare the bar heights related to the scale. The Poor / Fair / Good / VG / Excellent rankings are there for this reason. Bear in mind however that what is usually called "Good" around here means "actually rather soft but manageable in a pinch" (Klaus, correct me if I'm wrong?) - hence anything below "very good" levels is something to be wary of. And if a lens is just "good" in the center at some aperture (like wide open) it means it's either pretty bad or - if you want to put it charitably - a "character" lens like the old Canon 50/1.2L.
