How to train your Grey?

I just read the following at a website and was wondering what experienced Grey owners thought?

How to Train an African Grey Parrot – Part 1

African Grey Behavior Modification
You might choose to begin your parrot training with behavior modification techniques. African Grey behavior modification is best achieved when humans behave as caregivers, guides, teachers, and parental figures. An African Grey considers himself your equal, and expects respect from you. He does not seem to understand punishment, but remembers who punished him. Parrot training for an African Grey should give choices rather than punishment.
Choices
One behavior you may want to modify through your parrot training is that of the adolescent parrot that refuses to leave his cage when you give the “up” command. He knows the word “up” and associates it with hopping to your fingers to leave the case, but he develops a stubborn, independent streak. You can train an African Grey Parrot to make a choice in such cases: obey your command, or come out in a towel.
The Towel
At the beginning of your parrot training course, your parrot may, by default, choose the towel. He knows little about it, but is determined not to obey your “up” command. After a time or two of leaving home in a towel, however, he will choose to obey and step up on your fingers.
Parrot training to the towel will require that you set yourself to be gentle, calm, and unhurried. Then follow these steps.
* Fold a bath towel in half.
* Place your hands beneath the towel for protection.
* Move the towel into the cage, and gently enclose the parrot.
* Be careful not to squeeze the parrot’s breast.
* Grasp the parrot gently around the sides of its body.
* Holding it in the towel, slowly remove both from the cage.
* Gently place your parrot on the cage top, holding it until it is secure on the perch.
* Remove the towel carefully.
* Scold the towel firmly as you lay it aside.
* Speak to your parrot in a happy, calm voice.
The next time your African Grey refuses to obey your “up” command and leave his cage, simply show him the same towel and ask, “Do you want the towel or do you want to come up?” If he still refuses to leave home on his own, repeat the towel process.
As you continue your parrot training, adapt this same behavior modification technique to other behaviors you want to change.

Reward Natural Actions
If you expect your parrot to understand and obey your words from the beginning, your parrot training is off to a poor start. Your African Grey does not know what you mean when you ask him to lie on his back. You might as well be asking him to install a new mother board in your computer.
That’s why the goal of your early parrot training will be to get him to do an action naturally. It doesn’t matter what the action is, as long as it is agreeable to you and not bad behavior.
With a supply of treats nearby, take your African Grey from his cage and place him on a perch. As he sits there, hold up one treat. The second he looks toward the treat, say, “Good.” Say it before he takes the treat, and don’t give the treat until you have said, “Good.” This is step one of any parrot training.
Why do you do this to train an African Grey? That one word will come to mean a lot to him. In no time, he will connect the sound of the word “Good.” with his treat. He will know that the treat always comes after the word “Good.” and never before. He will want to please you so that you will say “Good.” and trigger the treat.
Since parrot training involves a great deal of repetition, continue training him in the same manner. Hold up a treat, wait for him to look at it or reach toward it, say “Good.”, and give him the treat.
Save Treats for Training
You want your African Grey to connect good behavior with treats. To be sure that happens, you should always save treats for parrot training time. Also, refrain from giving his favorite treat when he is in the cage, unless he’s doing an action you want him to do. Parrot training is best done outside the cage, with saved treats offered only then.
