Average Yahtzee scores

What are the average yahtzee scores for the these final outcomes?

1.) NO yahtzee
2.) ONE yahtzee
3.) TWO yahtzees
4.) 3 OR MORE yahtzees.

I note the complicated Wikipedia page with warning thats its too complex...
=======================================================

FWIW, my strats

1.) Quads
score in number box to receive 35 point bonus, else
score in the Quads box if > 22 points, else
score in the Triple box if > 22 points, else
score in Chance if > 22 points, else
score in score in Quads box if > 18 points
score in number box

2.) Full House
if the Triple causes a 35 point Upper section bonus, score there
If the Full House has a total of 25+ score in Triple or Chance, else
score the Full House

3.) Triples try to improve unless such Triple scores the 35 point Upper bonus.

4.) Two Pair- keep combos of 4-5-6 Two Pair, otherwise roll the One Pair needed.

The First Quad >18 and Triple >22 go to the LOWER section. Chasing the bonus costs points (abt 7.5).
