Growth %
Days of history at least
Growth % = subscribers gained ÷ subscribers at the start of the window, with the start counted as at least 1,000, so a jump from 50 to 5,000 can't top the list. Channels under 90 days old whose tracking began after launch get the window start estimated from their creation date (0 subscribers then, a straight line up to the first real reading; under-counts a late boom, never inflates it). Marked * on the card.
