-- NBVA's own points scheme (as printed on the points-scheme image supplied 2026-09-14), a
-- plain place x division lookup table -- unlike Module:ABVRS Points, there is no single
-- base(place) x multiplier(division) formula that reproduces every printed value exactly
-- (checked: a per-division multiplier reconstructed off the AAA column and rounded gets
-- most cells right but not all, e.g. 2nd/BBB prints as 51 where a clean 0.112 multiplier
-- would round to 50) -- so this stores the 12 x 6 grid literally instead of reverse-
-- engineering a formula the source doesn't actually follow everywhere.

-- 12-team draw. A 16-team NBVA event still renders 16 rows (so the table's shape matches
-- what abvrs_draw_size asked for); places 13-16 just come back blank until NBVA publishes
