I submit that none know unless they have computed the answer beforehand. And even if they knew the answer it would be impossible to judge accurately. And I guess that first 1/4 loop establishes the radii of all the corners.

<div>Your assumption is correct. You must pull slightly before reaching
center on the inbound side and push slightly before center on exit to make the 2
45 degree uplines match. You only cross 'center' on the downline in the
knife edge portion of the 2 of 4.</div>
