03 / Checks
How far this state was checked.
Platform ties: Texas' table was built by hand; elsewhere ties are matched automatically. In 6 more states a random draw of ties and of practices with no tie found was searched by hand against a bar set before the search; a check not met is shown as not met, and its failed ties were taken out. The other 44 states have automatic checks only.
