How a single Palworld card price is calculated
A Palworld card price on Pal Stars is the median of validated same-day listings, not an average. The median is taken after outlier rejection at three median absolute deviations, so a single fantasy listing cannot move a card, and the result is then sanity-banded against the printed-rarity baseline so impossible data is dropped rather than published.

Why median, not average
Card markets are thin and skewed: one seller asking ten times the going rate drags an average badly but barely moves a median. Using the median is the single biggest accuracy decision on the board, and it is why the Market column usually sits well below the High column on chase cards.
Outlier rejection in plain terms
The run measures how far each listing sits from the median in median-absolute-deviation units and discards anything beyond three. On a typical day this rejects thousands of samples site-wide — mostly mislabelled lots and aspirational chase pricing — and those rejections are counted in the sync report.
Low, high and market together
Low and High are the validated extremes of the same sample, so the spread tells you how much agreement exists. A tight spread means a liquid card; a spread several multiples wide means the market has not settled and the median deserves less weight.
Freshness rules
A quote older than four days stops moving the market price. That prevents a card from appearing to hold a price when nothing has actually been listed for a week, and it is why some rows switch back to the index baseline between listings.
The flags that qualify a number
Thin sample, stale feed, modelled price, sources disagree, sold under ask and sold over ask each mark a number that needs a second look. Read the flag before acting on the price — a thin-sample chase card is a starting point for negotiation, not a valuation.
