By the way the calculation is wrong for Jo ! It's adding in that earlier one point, which is a non counter. So, she is only up a net 24 points to 485 points ( with 30 replacing her current 16th counter of 6 points ).
Sorry, couldn't resist it ! I am aware that that is liable to happen when there are points from more than one tournament, and is very minor issue that would have been readily sorted.
The table perfectly showed Jo winning 30 points this week and moving ahead of Anne in the rankings.
