you will get the checkpoint score nearly in case (B) (and therefore especially (C)).
We are working on guidelines for the judges to have more consistent judging, you can check them here: https://github.com/TechnoX/guidelines-rcj-rescue-judges, quote:
- "Reached checkpoint" is defined as "more than half of the robot is within the tile marked with a checkpoint marker, when seen from above. ".
The definition is the same as already stated in the Maze rules. We noticed this lack of definition and will write it on our list to improve in the rules for next year. Sorry for confusion!
