7 runs each: L157 near 55.4% but a 16.7 ms worst tick (UpdateChunks/level sort/overlay); L160 tick-safe but lower
all-around near and later arrival; both: forward cone 25.2% and p99 <= 11 ms, but worst tick up and a 14.3 ms run.
Also found: voxel.StreamingIncrementalDesiredSet defaults to 0, so L165/L166 gains need it enabled.
