It will be interesting to see the number, the main aspect where IRC is not so user friendly is the difference between real life performance and the IRC number, especially looking at boats such as Farr 1020 compared with Ross 930s the IRC differences are huge with the 1020 being rated as much slower than the 930 but in real life it is much different especially when upwind sailing is taken into account. 

A modified version would be good and could be much closer to reality and NZ yachts I reckon.

We cannot direct the wind but we CAN adjust our sails

If you have a light boat that will take off downwind and in the right conditions (a race entirely downwind in decent breeze) will win by a big margin - IRC seems to take this into account. So for windward/leeward or a course changing direction the fast downwind boat will get smacked on rating. A Ross 930 is 2.2 ton, a Farr 1020 is 3.7 ton so there it is.
