Is this difference real?

Two rows of a breakdown table, and the table you found them in. Move the counts to see how much of a gap the data can actually carry, then move the last slider to say how many rows you scanned before this one caught your eye.

The range each row's own click count allows. Where they overlap, the data cannot tell the two rows apart.

The bar the standout row must clear, as the table grows.
