House points are known ICly since students pass by the hourglasses every morning as they enter the great hall. OOCly there will be no numbers, just these comparative heights.
The points here are calculated precisely to reflect the average amount of activity per house, but we will not give exact activity numbers to discourage people from designing their journals/logs/owls around this system. Heights also reflect quidditch games and (very rarely) wide scale disciplinary infractions.
