Chris,
You'd expect to be able to get 3-4 days of advanced data to populate a guide
with, in reality you can often get as little a six hours and that's it. The
mandatory side of the spec is weak in this area. six hours is fine for Now /
Next but of little use for anything else.
Depending on your needs, your mileage may vary.
Regards,
- Steve
