When usage_pct == 0 (pool utilization 0%), the condition 'rand_.Next() % 50 <= usage_pct' incorrectly filtered allocations with probability 1/50 = 2%, because rand % 50 == 0 satisfies <= 0. Change to '<' so that usage_pct == 0 yields 0% filter probability, matching the intended behavior: filter probability scales with pool utilization, and 0% utilization should never filter.
