Dave agree on the 7F which has come about by people actually bringing in 7F specialists rather than running milers as they have in past seasons.

On the irons it wasnt a guess, watch last years races and the pace is actually considerably slower than this year as it is over the 2 mile and the14F races.
The 14F races and to a lesser degree the 2 mile races benefitted with many record times yet the irons, particularly the 20F races finished considerably slower than last season.
