Impact XP is what you build: businesses, and skills that serve other people. What you build and give can outweigh what you measure, so it will often count for more than Stat XP. Its formula is still being finalized, so the number will likely change. For now each item scores by how few people share it, and items without a sourced count wait at 0.

XP = 100 × standard deviations past the average of each stat's reference group. One SD beats about 84% of that group, two about 98%, three about 99.9%. Nothing is capped, and below average subtracts.

A stat's XP and its percentile are one fact in two units. Beats always means the group that stat's source measured, named on each row. Stat XP is every scored stat added up. HOQ, the headline number, brings Stat XP and Impact XP together and rewards breadth across the four dimensions; it is an estimate (*) until Impact XP is final.

A sample card: Mara is fictional, and so is every result on this card. The references are real. Body, lab, heart and performance stats use the women's rows; sleep, close friends, education and travel use surveys of all US adults, since those aren't split by sex here. Lifts are scored against female lifters at her bodyweight (138 lb). Body fat is compared against NHANES DXA percentiles for US women 20–59. The run converts the 6:58 mile to a 1.5-mile time (Riegel formula) to match the study's women's group.

Sleep, close friends and education are scored here against published surveys to show how those attributes read once they're measured. They aren't in the scoring engine yet, so a real card shows them as open slots until they are.

Mara hides two sections: mind and sexual health. They still count toward her Stat XP and Rarity; what's in them stays private, and members can ask to see them. Yes/no results score by how few people share them. Not scored, and why: ferritin, vitamin D and the rest of the labs (healthy is a range, not a ranking) · the half marathon and 5K (no matching population spread yet) · blood type (not better or worse).
