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: Marcus is fictional, and so is every result on this card. The references are real. Body, lab, heart and performance stats use the men'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 male lifters at his bodyweight (166 lb). Body fat is compared against NHANES DXA data for US men 20–59. The run converts the 6:40 mile to a 1.5-mile time (Riegel formula) to match the study's men'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.

Marcus hides one section: mind. It still counts toward his Stat XP and Rarity; what's in it stays private, and members can ask to see it. Yes/no results score by how few people share them. Not scored, and why: the rest of the labs (healthy is a range, not a ranking) · the 5K and pull-ups (no matching population spread yet) · blood type (not better or worse).
