the largest gains in wall clearance.
This metric might be important when traveling with bigger party, but I would not pay too much attention to it.
It basically shows how much close to the wall the path happens to be.
Sometimes it matters - when old version were hugging every wall just to close the distance between the path and the line to the target, it clearly is now an improvement.
But sometimes this number just says "we're now searching on the tiles' centers, we can't physically get as close to the wall as the old algo".
Safer paths: 2411 out of 4663 requests passed farther from walls, showing only 24 exemplary illustrations.
