What kinds of throwing is most beneficial to pitchers?

A baseball pitcher's long toss throwing program should include both 120 feet long tossing and maximum-distance long tossing.

Here's what I mean:

If, for instance, you throw throw six days a week on the throwing program you're currently on, use four of those days to long toss at around 120 feet, and then back it up to maximum distance for the other two days. (You maximum distance is determined by the point at which you can't reach your throwing partner in the air.)

Multiple distance long-tossing varies the stresses placed on the arm and builds the greatest amount of strength. (Much like performing different reps and types of core exercises strengthens your abdomin a little differently from one another).

The reason I limit the "all-out" long tossing to just two days a week is because my college pitchers are throwing bullpens, performing on-field throwing in drills, and pitching in games on the other days.
