Add an R4 term or correct that penalty, and screen until the median ρ is 0.5 or more for the three measures. Step 2: a work counter for each new term. Step 3, the gate of the default: the seeds 6 to 10 on `screen-v3` and the dense window of 500 boxes. Gains on ink and R1 with Holm, and R4 drops beyond the floor on 2% of the inputs or fewer. The claim gives the median and p10 of each measure, the share of the inputs that move and the time ratio. A pass is a MINOR.",
