You can think of these 5 seconds as a penalty robot is required to serve for entering a blue tile. They have to be served before exiting the blue tile AND making any sort of sideway movement/adjustment/turning. Basically as long as the robot is moving forward it can stop at any point before leaving this blue tile.
So in the example you presented above, LoP would occur in state No. 4.
We will add this clarification to the rules as well.
I understand from your answer that LOP occurs in state No.4.
and LOP occurs if the robot enteres the blue tile and leaves the blue tile without stopping for 5 seconds.
( Rule 4.5.1-c is not correct, so please fix it )
I ask again.
At what point does a LOP occur when a robot enters a blue tile and passes through it without stopping?
4-1. When part of the robot is out of the blue tile
4-2. When half of the robot is out of the blue tile
4-3. When the robot is completely out of the blue tile
I understand it.
so, Rule 4.5.1-c →
LOPs occur when robot enters blue tile (robot visits blue tile), after that robot exits blue tile (robot visits other tile) without stopping for 5 seconds
