What happens when I reach my goal total / end date?
Using the commitment dial, you can set a goal total (the amount you want to get to, e.g. number of pages in a book) or goal date (the date you want the goal to finish, e.g. the date of an exam).
What happens when I reach my end date?
When you reach the end date, your goal will go into the "success" state, and offer you the option to archive or restart your goal. Restarting works pretty much like restarting an archived goal.
The akrasia horizon doesn't apply to archiving your goal when it's in this state.
What happens when I reach my goal total?
Once you've reached your goal total, your goal may continue until the goal date or implied goal date. For example, if you said you want to get to a total of 100 by 20th May, then the goal will continue until 20th May even if you've already hit 100, but it won't require more data. Once it reaches that end date, it'll go into the success state as mentioned above.
If you have your goal set up by goal rate and goal total, there's still an implied goal date as well. If you said you want to reach 100 in total at a rate of +10 per day, then your goal will go into the success state after 10 days -- even if you get to 100 after 5 days. Again, it won't require more data, it just won't go into the success state until the implied end date is reached.
