sampled 6 of 699 results across 19 hosts. In every sampled payload, adding spatial correlation from 0 to 2 or 5 turned most conditions from no highway within tens of millions of steps into fast highway formation, often in only thousands to hundreds of thousands of steps. Within those correlated runs, the moderate stripe amplitude 0.22 was usually faster than the strong 0.42 stripe and dramatically faster than the unstriped baseline at intermediate density, while the uncorrelated moderate-stripe condition often still failed completely.
