If you miss-quote a W3W word then the algorithm is likely to put you someone completely different on the planet, and the error is much more obvious. In the same way mountain rescue probably urge you to use a compass and paper map, but don't understand that a digital map on a phone with GPS is probably easier to use, or that people might baulk at buying paper maps for all their walks, so set off without anything. The best can be the enemy of the good here.
If the last message with the W3W text is with the final burst of network or battery, being 1km away is much better than somewhere completely different on the planet.
