AMJA card

Cross-comparison

partial — sources agree on some points and are silent or divided on others

• [1] the scorecard is published annually by both the National Mah Jongg League and the American Mah-Jongg Association; the AMJA card is the second of the two
• [2] describes the annual card as an artefact and how the NMJL and AMJA cards differ in form
• [1] the AMJA is named alongside the NMJL as one of the two bodies publishing an annual card, and the two are described as having minor scoring differences
• [3] not relevant to this node; recorded only to note that amja.net itself could not be read, its TLS certificate having expired, so no primary source for this node was obtainable

Reading it

Two sources confirm the AMJA card exists as the second of the two annual American cards and that the NMJL and AMJA differ in minor scoring details. The association's own site could not be read: amja.net serves an expired certificate, and it was not fetched over an unverified connection. So the node is attested but not primary-sourced, and no source read here describes how the two cards differ in practice.
