It's not too hard (insert joke about something hard), you can simply look at the picture up top (insert another joke about being on top) and check the amount of points next to Grinbutts.
The points in the score table are essentially just simple dials showing the number in base 10. So two dials means a number that is XX. If the left dial is on the first dot that's a 1, on the second dot a 2 etc. Say left dial is on 1, right dial is on 8, well, that's 18.
