sampled GPU runs usually landed at interior delta_c_estimate values around about 2.06 to 2.59, with occasional larger values near about 2.79 to 3.29, but last_split_fraction was usually 0.0 and only intermittently reached about 0.33, 0.5, or 0.67. When a gap did appear, the detached fraction usually sat near about 0.25, 0.50, or nearly zero rather than the planted 0.20 minority target, leaving minority-error values commonly around about 0.20 to 0.30 and often worse than the built-in tolerance.
