Practical Data Known limitations
These are mistakes that the tool makes on real pages.
The first ones cause a check to fail. CI accepts these failures, but no other failures. The last ones show only on live pages.
Heights written as 6-7 (feet and inches) are not read as numbers.
They have the same form as a range (20-25) or a win-loss record (12-4). The column gets ordered labels: the order is correct, but the steps between heights are not to scale.
Example: Ht in Thunder: roster and stats (shade or ignore).
One-letter grade codes can get the wrong order.
For card rarity (C, U, R, M), the model puts M (mythic) below U and R. Full names, such as Mythic Rare, get the correct order.
Example: R in Scryfall checklist (order of labels).
A close decision can change from one run to the next.
The model's answers are not fully repeatable near a threshold. Two runs of the same question about death tolls in two earthquake tables gave a shared scale once and separate scales once.
Example: Death toll in Earthquakes of 2023 (shared scales).
Only HTML tables are read.
Some pages build a grid from div elements. It looks like a table, but it is not one, and the extension does not shade it. MTGGoldfish now shows its price lists this way. Our copy of the page has tables, thus its checks pass; the live page has no table to shade.
Example: MTGGoldfish: Modern Staples.
