I don't think most speed drawing is designed to make you learn but just see certain techniques if you know how to use those programs as well as they do.
More correctly , it's more like educating them (or rather showing a way , their way) in putting all learned and mastered foundations into motion by creating the very first proper , finished artwork .

Speedpaints are still a form of tutorial , but it's definitely not for beginners , that's for sure .
One thing I've noticed after scouring through the nets for writer's tutorial videos is that they all fall roughly under the same circle as the said person Lumaria's mentioned there , so far .
