New update to User Registration - Edit Feature

I am sorry, but I am confused.
I created a User information form. I made it the registration form.
When the user hits register, they get the form. A WP user is created. The info is available to view in GF view and downloads. YEAH!

I created the new update feed. Wouldn't let me use the same form (WHY?). So I created a duplicate of the register form and called it update. Created the update feed. Bummer, now two identical forms to keep in sync.

I created an update page and brought in the "update" form. No values are populated to edit.

Is there any actual documentation as to how to achieve this seemingly simple process of letting a user signup and then edit their own information?

Although the GF takes over the new user/register hooks, if a user logs in to WP and goes to edit their own user data, the update process isn't taken over, and they are shown the - what is now foreign to them standard WP user form, which has things on it they never saw before, and NOTHING they probably want to update like their address or phone number.

Is there any clear and concise documentation on how to achieve this now with the new update? Reading the forums and Dox (none I can find that are updated) are maddening at best. This should be simple. If I missed something, just point me to it.

Thanks.

First of all, I think it's great that user updates are implemented.
I also agree with @electricscribe that there is room for improvement to make the admin life simpler.
It's certainly a pain that all forms need to be duplicated before they can be updated. I think @electricscribe's idea will work great for small forms.

However, I also see a benefit in the way it is done right now. We have a lengthy form with 4 steps. We will probably break up the form into 4 forms for updates and link to the 4 forms when a user is logged in. Why? If an end user wants to update one field only, he'd have to go through 4 steps every time he wants to change something.

I think the thing that is getting lost is, HOW do I give the user the ability to edit his details? I duplicated the registration form, added it as the update user form. I put it on a page, but when the user goes to it, their current information isn't populated to edit.

And, like the register form gets auto-hooked into the WP user registration process, the update form should be auto-hooked into the WP user update process.
