Percentage deviation of actual block production time from the 10-minute target. Positive (slower blocks) means downward adjustment pressure on difficulty, negative (faster) upward pressure.
Why: Tracks block pace against the 10-minute target. Fast blocks mean more miners are online and upward adjustment pressure on difficulty; slow blocks mean miners are dropping off and downward pressure.
