If you take Riccarton as an example (correct me if I'm wrong Pitty) but I think they've been running about 27 meetings a year there on the grass and my understanding is that the committee feels that has the grass course pretty maxed out. If they go to 40 meetings there, then you'd think that might mean say 15 of them on the AW, mostly over winter. I guess there's also the possibility that some meetings could be run using both courses as is common in the US between dirt and turf.
