[Zodiac Rating] VIRGO

[eggyk]

Is it worthwhile adding a criterion for good dating, moving the more relevant examples up a bit and those that are too late down?

No, I don't think so. If the zodiac is truly representative of a certain time period, that time period should end up having higher scores on average. Someone in 1425AD could have had access to, and copied from, manuscripts from the 1200s and 1300s, and manuscripts from the 1500s may have copied from manuscripts from 1425. 

So we shouldn't assume what is or is not relevant; the data should lead us agnostically to those answers.
