DEFAULT_MAX_REPLICATIONS_PER_SYSTEM

Default cap on the Rinott second-stage sample size per survivor. Chosen large enough to preserve the exact indifference-zone guarantee for moderate variance-to-δ_C ratios (a standard-deviation-to-δ_C ratio up to roughly 50 with the usual Rinott constant) while bounding the pathological case where a noisy objective and a tight δ_C would otherwise demand millions of replications.
