The stock RWMaxIterations (25) is only the Simulation's setup value; TU3
solves with 50 on every gameplay frame. With 25 the constraints converged
less: wheels sank ~10x faster at rest, the ollie deck sat ~1 cm low and
the jump velocity the pop sound reads was too small (rolling ollie
0.21-0.29 vs retail 0.50), so pops picked the quiet row.
Maps validate identically; water traces stay within expectations. See
docs/hails-additions/12-solver-iterations.md.
