Just for the curiosity I put an excel together. I come out with 740 for Ireland after the Wales match. 3 points different to that site. EalingGreen, if you're as sad as me you could do the same for Northern Ireland and work out their ranking. It's only a couple of days wait anyway.
Anyway, here's the file for anyone that wants to see how the points are calculated:
