What Does "Complete Diary" Actually Do?

Tango_Bravado

Does the "Complete Diary" button actually do anything? When I click it, it gives me a tidbit of info like "If you keep doing this you will be X lbs in X weeks" or something like that. Is that the only point of it? Or does it have some other effect in reports or something?

Thanks!

It also posts a message on your newsfeed stating that you completed your diary and if you were under your calorie goal (if you have that option for newsfeed posts activated).

The prediction is quite unreliable too.

No practical use to it, I haven't closed my diary in years.
