Since the latest GrepolisUpdate, detecting NC's is now harder for the bot, since its possible to launch an attack with invisibility helm. Lets say the user is using the speed boost item + the invisibility helm, it would be 40% "less" time the NC takes to reach your city. In an attempt to counter that we added 35%, 45% and 55%.  Also remember that "Set Sail" adds another 10%, which would make it a total of 50%. We'll continue testing.
Remember the higher the deviation the higher chance of detecting false positives.
