If the crock pot cooking time for beef is 8 hours on low, what is the cooking time on high?

Know that uncooked meat and vegetable combinations usually require 7-8 hours on "low" (about 200 degrees), and about 4 or more hours on "high" (about 300 degrees). Remember to add time for "high-altitude" cooking! (Cooking times/temperatures are roughly equivalent to oven baking in a covered cerole/pot at 350 degrees for 1 hour.)
