Behind the median
Everyone here with an Eng Scorer read, placed in their caliber tier.
- 36%Exceptional or strong12 people
- 48%Solid16 people
- 15%Emerging or unproven5 people
33 of the 46 people here carry an Eng Scorer tier.
12 of the 33 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.
