61 of the 112 people here carry an Eng Scorer tier.
22 of the 61 people here with a read sit in exceptional or strong, the top two of the five tiers, 36%. A tier is the band a caliber score falls in, so this is the same measurement as the median on the caliber card, opened up. A tier holding fewer than 3 people is printed with the one next to it, because that few is a person rather than a pattern.
