Super League came up with a Percentage system to take into account cancelled matches. As they award 2 points for a win, 1 for a draw and no BP it's easy to do.
If Premiership Rugby applied a similar system it could have been based on the percentage of points available based on 5 per match being the maximum any side can get.
Had they applied this system, the League table would look like the attached image.
The biggest changes to the table is we'd be sixth, ahead of Leicester, and Bath and Gloucester would swap places.
