N73VR is harsher than the type on utilization; D-AGBF is gentler on engines and brakes; 9H-NEAH is harsher on fatigue and utilization. All three tails have an untracked stretch of two weeks or more: 9H-NEAH 39 days, D-AGBF 33 and N73VR 27.
Not on the board: N927CA, D-ATON (no tracked flights to grade).
GentlerTypicalHarsherContextGrade is against the peer group: typical is its middle half. Rank is within this set, gentlest to harshest. Each chapter takes the grade of its lead metric (method).
Spotlight
Pick one tail to read the set against. Nothing is promoted by default.
Pick a tail above to see where it reads gentler or harsher than the other 2 on the board, measure by measure.
Gentler and harsher here are relative to the other tails on this board. The square and tint still show the grade against the peer group, so a tail can be the gentlest here and still harsher than the type.

Leg length is context. Shorter legs are what lower hours per landing, so grading both would count the same thing twice.

Appendix A2
Method
Every tail on the board is read from its own flight track over the same window, 1 Jan 2025 to 29 Aug 2026, and placed against the same peer group. Hours are estimated from time in the air; the logbooks have the real totals. Airports and exact dates are left out on purpose.
Two readings, side by side. Colour grades each tail against the peer group: between the 25th and 75th percentile it is typical; outside that band it is gentler or harsher, depending on whether it eases or adds to that kind of wear. Rank places each tail within this set only, gentlest first. A tail can be gentlest in the set and still harsher than the type. Each chapter takes the grade of one lead metric, fixed in advance: hours per landing for fatigue, coastal nights for corrosion, short-runway departures for engines and brakes, flights a month for utilization. Context rows are shown without a grade or rank. Each tail’s grades are the same ones its TailCheck report shows.
