Credit Ratings

Formula

R(c)=−∑t=15wtlnpt(c)w=(1,1,1,2,1)
S(c)=80+3.6(k+R(c)−QkQk+1−Qk)

p is the fraction of the edition with a trait value as uncommon as, or less common than, this Credit’s value. Trait order: palette, active bits, occupied cells, eights, print. Eights carry twice the weight.

Q0 … Q200 are the rarities of the 122,154 Credits at every half percentile, lowest to highest; Qk ≤ R(c) < Qk+1; at or below Q0 the score is 80, at or above Q200 it is 800. Points and rarities are fixed point (× 10⁹, rounded). Scores are kept to four decimals, rounded down, and shown truncated to two. Ties share a rank.

The Statements contract computes this same score for every Credit (CreditScore). A Statement’s Credit Rating is the sum of the scores of every Credit burned into it, overprints included; its metadata shows that sum rounded down to a whole number.

“As rare or rarer” is the share of Credits whose value occurs no more often than this one, including ties. Lower means a less common trait.

Methodology / 4.0.0

Reference: the frozen original allocation of 122,154 unique Credits. Counts remain fixed when works trade or are burned. Ownership and burn status are not verified.

For palette, active bits, occupied cells, eights and print, sum the population counts of trait values occurring no more often than the selected value, then divide by edition size. Each value’s points are its negative natural logarithm, in fixed point (× 10⁹, rounded); eights count twice. A Credit’s rarity is the sum of its five points. Double weighting eights is an editorial choice.

A curve through the edition’s sorted rarities, 201 points at every half percentile, places each Credit on 80 to 800, in a straight line between points. Integer arithmetic, in ten-thousandths, exactly as the Statements contract’s CreditScore computes it; a rarer Credit never scores lower. Display truncates to two decimals. Ties share scores and a competition rank; Credit number breaks display ties only.

No token-specific exception or background tier applies. #11469 ranks first under the same formula used for every Credit. This is a descriptive index, not an independent joint probability or valuation. Traits can be correlated.
