The reason is simple mathematics. For every interval (0, >>> n] the relative covering is 1/10, independent of how the hats are >>> shifted.

Limit theory only works if the limit actually exists You can get things that APPEAR to reach a limit, but actually don't. You are just confirming that yoiu mind HAS benn exploded by the contradictions of using finite logic on infinite sets, and that has left the great big "dark hole" in your logic, that doesn't actually exist.
