Builders often order framing lumber from an allowance: one stud per foot of wall, or studs on centre plus a few per opening, then 10% waste. We set two such rules against the counted, cutting-stock-optimised order from wall-framing-takeoff, on the same walls.
At 16 in o.c. the per-foot rule is +7.7% on the example house and +1.9% on a CC0 generated plan. It is not accurate in general: it ignores spacing. At 24 in the counted order falls to 1972 and 2222 lineal feet, the per-foot rule stays put, and it over-orders by 26.5% and 16.7%. The on-centre rule follows spacing but stays 16 to 25% high, from its four-stud-per-opening allowance and plate count.
Caveats: two invented or generated houses, no real permit set or builder order, and the rules are our reading of common practice, not a standard. Header sizes are left out. Reproduce with node allowance-bench.mjs.
