Row 50's two numbers, ROM-gated from the forest checkpoint. Before, on main:
MOVE n 940 starts and 838 blocked, 11 battles entered and 10 ended, worst 503
macros, median 48. After: 51 starts and 0 blocked, 13 entered and 13 ended,
worst 283, median 43, and the fly leaves the forest north through the gate.
The blocked share is the assertion the row is about; the median is what it
buys, and the worst battle is a tail rather than the run.
