AqMoon,
Thanks - hindsight of course is always 20/20, but one has to start somewhere. Regarding noon charts, the only chance we are taking is the position of the Moon since we are not using the natal angles and house positions. So I would expect this to work more often than not. One idea would be to find out when during the day the majority of foaling occurs, and then set all charts around that time. Perhaps sunrise charts would work better if most births are at dawn.
The Preakness should be fun. Post time is 6:05 pm, and the racetrack is in Baltimore MD.
We could also do major UK races. The Irish 2,000 Guineas is on May 27, Tatersalls Gold Cup May 28, Oaks June 2, Derby June 3. So there are quite a few big races coming up in the next few weeks.
